Door Manufacturer in China for Global Projects
There is no single standard door size that applies to every building, room and project in the Philippines. For steel entrance doors, 800 × 2100 mm and 900 × 2100 mm are recurring single-door sizes in TOF’s Philippine supply experience and in public Philippine retail listings. TOF also commonly encounters 1200 × 2100 mm unequal double doors and 1500 × 2100 mm double-leaf doors.
These figures are useful for catalogue planning and preliminary quotations, but they are not a substitute for an approved door schedule or site measurement. Before production, the buyer must distinguish at least five different dimensions: the nominal order size, door-leaf size, frame outside size, structural or masonry opening, and clear passage width.
The most important purchasing rule is simple:
Do not treat the door leaf, door frame, construction opening and clear opening as the same measurement.
This guide explains the common market sizes, relevant Philippine minimum requirements and the information an overseas manufacturer needs before releasing a project order for production.
The following table combines TOF’s company-reported Philippine experience with publicly visible local product sizes. It describes recurring commercial dimensions—not mandatory national standards.
| Door type | Recurring preliminary size | Practical note |
|---|---|---|
| Single steel entrance door | 800 × 2100 mm | Common TOF Philippine order and public retail size |
| Single steel entrance door | 900 × 2100 mm | Common TOF Philippine order and public retail size |
| Unequal double door / active leaf with secondary leaf | 1200 × 2100 mm | Common TOF reference; leaf split must be confirmed |
| Double-leaf steel entrance door | 1500 × 2100 mm | Common TOF reference; clear opening depends on leaf and frame |
| Passage fire door | Often similar to project steel-door openings | Must follow the approved fire and egress design |
| Pipe-shaft door | Frequently smaller; around 600 mm wide and 1600–1800 mm high may occur | Preliminary commercial observation only; project-specific |
| Bedroom door | Project-specific | Relevant housing minimums and finished opening must be checked |
| Bathroom or toilet door | Project-specific | Moisture, ventilation, privacy and accessible-route requirements may change the door |
TOF reports that 50 mm and 70 mm door-leaf thicknesses are common for the steel entrance-door products discussed here. Leaf thickness is a construction parameter; it does not determine the opening width or prove a performance rating.
No. They are recurring market sizes, not a universal legal definition of a standard Philippine door.
Public Philippine listings support their commercial relevance:
Together, these pages show that 2100 mm height and several widths between 600 and 1000 mm are commercially visible. They do not prove that every product uses the same measurement convention. A catalogue may quote the panel, leaf, door set or another nominal dimension. The buyer must read the individual specification and obtain a drawing.
Some Philippine rules state minimum clear dimensions for particular building types or accessible routes. These are design and compliance requirements—not ready-made factory order sizes.
The revised rules for Batas Pambansa Blg. 220 apply to economic and socialized housing projects covered by those rules. They identify the following minimum clear door widths:
| Opening under BP 220 | Minimum clear width | Minimum clear height |
|---|---|---|
| Main door | 800 mm | 2000 mm |
| Service or bedroom door | 700 mm | 2000 mm |
| Bathroom door | 600 mm | 1800 mm |
Source: Revised Rules and Standards for Economic and Socialized Housing Projects.
These dimensions should not be presented as the standard order sizes for all Philippine homes. Their scope is specific, and the values are minimum clear dimensions. An 800 mm nominal door set does not necessarily provide an 800 mm clear passage after the frame, stop, hinges and open leaf are considered.
The Philippines’ 2024 revised implementing rules for BP 344 state that doors subject to the accessible provisions should have a minimum clear width of 900 mm. They define the clear opening as the distance between the face of the fully open door at 90 degrees and the door jamb. For double-leaf doors, the rules state a minimum clear width of 1800 mm.
The same rules also address thresholds, manoeuvring space, hardware position, operating force and other accessibility details. This illustrates why a nominal width alone is not enough. A buyer cannot assume that ordering a “900 mm door” automatically produces a 900 mm accessible clear opening.
The project architect, accessibility professional and local approving authority should determine which openings must comply and how the requirement is shown in the approved design.
A fire door does not have one universal Philippine standard size. Its dimensions and configuration must follow the approved fire and life-safety design, required clear egress width, wall construction and the scope of the applicable test or listing evidence.
An oversized, double-leaf, glazed or louvered fire door may not be covered merely because a supplier has a certificate for another door. The proposed leaf, frame, hardware and size must be checked against the supporting evidence and project approval.
This is the commercial reference used in catalogues, enquiries and quotations, such as 800 × 2100 mm. It helps identify the intended product but may not reveal exactly where the manufacturer measures.
In TOF quotations, the stated door size is commonly used as the nominal opening or door-set reference supplied by the buyer. It should not be used as a production instruction by itself. The approved drawing controls the final leaf, frame and installation dimensions.
The leaf is the moving panel. Its width and height are smaller than some frame and opening dimensions. The exact deduction depends on the frame profile, clearances, threshold, seals, construction and intended function.
A product described as an “800 mm door” should not be assumed to have an 800 mm leaf without confirmation.
The frame outside size is the overall width and height across the frame. Frame profile, trim, return, wall condition and installation method can change this dimension.
For importing, the frame outside size is essential because it must physically fit inside the prepared construction opening.
This is the opening prepared in concrete, masonry, drywall or another wall construction before the complete door set is installed. It normally needs installation clearance around the frame.
TOF’s current practice for certain decorative steel entrance doors is described below, but it should not be applied automatically to every frame or fire door.
Clear opening is the usable passage after the frame and open leaf occupy part of the nominal width. It is the dimension relevant to accessibility, circulation, furniture movement and some egress requirements.
This is often the most important design dimension and the one most easily confused with the ordered door width.
For certain TOF decorative steel entrance-door sets with external trim, a nominal 800 × 2100 mm door may be paired with a recommended construction opening of approximately 820 × 2120 mm.
This provides approximately 20 mm of total additional width and 20 mm of total additional height for installation. It does not mean adding 20 mm on every side.
The external trim can cover the remaining installation joint after the frame is aligned and fixed. This is useful where the opening is not perfectly square, but the trim should not be used to conceal an opening that is materially outside the approved tolerance.
The 20 mm practice is a TOF installation recommendation for applicable decorative entrance-door frames. It is not a Philippine code rule and should not be copied automatically when:
For a plain or fire-door frame without decorative trim, TOF calculates the recommended opening from the actual approved frame, wall and installation detail. The buyer should not create the masonry opening from a generic “door size plus 20 mm” rule.
TOF uses a general doorway-measurement guide for customers across different countries. It is not a Philippines-specific measuring standard. For this article, the guide provides the factory-input workflow, while Philippine project drawings and applicable local requirements determine the final opening.
The TOF guide asks the customer to confirm five groups of information:
The site team should not report only one width and one height. A useful survey records the opening condition, multiple measurements and the finished construction references.

TOF doorway measurement guide for door direction, opening height, width, wall thickness, frame type and threshold.
The TOF guide instructs the customer to stand outside and face the door, then identify whether the opening is outside-right, outside-left, inside-right or inside-left. This gives the factory a common starting viewpoint.
Because verbal handing conventions still vary between markets, the final production drawing should also show the interior and exterior sides, hinge side, lock side and swing arc.
Record the width near the top, middle and bottom of the opening. Differences may indicate that the jambs are not parallel.
Record the height at the left, centre and right. If the final tile, stone, screed or threshold is not installed, state the proposed finished-floor build-up separately.
Measure the wall at several positions and identify plaster, tile, cladding or other finish layers. The structural wall thickness alone may not equal the finished wall thickness required for the frame.
A width and height can appear correct while the opening remains out of square. Record diagonal measurements and visible deviations where practical. The project team should decide how non-conforming masonry will be corrected before the door is released.
State whether the door uses a regular threshold, lowered threshold, no threshold, sill, drop seal or another transition. Confirm interior and exterior floor levels, drainage and the direction of any level difference.
The TOF guide separates exterior and interior opening layouts and illustrates different wall relationships. It also asks the buyer to identify how the frame sits relative to the wall rather than assuming that every frame is centred in the opening.
The manufacturer needs to know whether the frame will be installed into concrete, concrete hollow block, masonry, drywall, steel framing or another substrate. Wall shape, frame position, trim coverage, anchors and installation details may differ.
For a stock or project order, TOF requests confirmation of:
Hardware, glazing, louvers, seals and project-performance requirements should also be added where applicable.
Handing terminology varies between markets and companies. “LH,” “RH,” “left open” and “right open” can be interpreted differently depending on which side the observer stands and whether the door swings inward or outward.
For imported orders:
A door can have the correct width and still be unusable if the handing is wrong.
Based on TOF’s general order experience, including Philippine projects, recurring risks include:
The door may fit in width and height while the frame does not match the finished wall.
An out-of-square opening may be narrower elsewhere, creating installation problems.
The buyer and factory may use the same number for different physical dimensions.
Tile, screed, stone or another finish can reduce the available height and change the threshold relationship.
A sill, waterproofing layer or wall tile can interfere with the frame if it is not shown in the detail.
Incorrect handing affects hinges, locks, panic hardware, closers and installation sequence.
Apartment entrances, stairs, shafts, bedrooms, bathrooms, accessible routes and service rooms can have different requirements.
Projects often contain many sizes, openings and delivery phases. A door schedule should assign a unique opening reference and connect it to the approved drawing.
Recommended fields include:
| Door-schedule field | Why it matters |
|---|---|
| Project phase | Aligns production and site programme |
| Building and floor | Supports packing, delivery and installation sequence |
| Room or opening number | Gives every door a traceable identity |
| Quantity | Prevents duplication and omission |
| Nominal and rough-opening size | Separates commercial and site dimensions |
| Frame outside and depth | Confirms fit with the wall |
| Leaf and clear-opening size | Supports function and compliance review |
| Handing and swing | Controls frame, hinge, lock and installation preparation |
| Wall and threshold detail | Controls fixing and interface conditions |
| Hardware set | Connects preparation to the approved components |
| Finish and sample code | Controls visual consistency |
| Drawing number and revision | Prevents production from an obsolete drawing |
TOF organizes complex project orders by project phase, building and floor for production, packing and warehousing. Labels or barcodes can be connected to the opening references when included in the confirmed order requirements.
Where dimensions are complex, TOF engineers may provide on-site opening measurement after the location, timing, access and scope are confirmed. This is a paid professional service regardless of whether the final order is awarded to TOF. The exact fee, travel arrangement, deliverables and responsibility boundaries must be agreed in writing before the visit.
The project architect or contractor remains responsible for approved design dimensions and site readiness unless the contract expressly assigns another responsibility.
For a first order or complex project, TOF recommends the following sequence:
Door schedule and site information
→ Technical review
→ Detailed drawings
→ Customer approval
→ Sample or first piece
→ Pre-production confirmation
→ Mass productionThe buyer should freeze the following before production release:
A late size change can affect formed frame parts, steel components, hardware preparation, packaging and delivery time.
TOF can manufacture customized sizes, with current company parameters reaching up to approximately 2600 mm in height and 2400 mm in total width, subject to door type, leaf arrangement, structure, hardware, performance requirements, transport and engineering approval.
This figure is a manufacturing boundary—not a recommendation that every opening should approach that size. Oversized doors may reduce the number of sets that fit in a container. They may also require an engineering review of leaf division, frame, reinforcement, hinges, hardware, handling and packaging. The final requirements must come from the approved drawing; no structural or performance change should be assumed without review.
For double and unequal double doors, always confirm:
Before ordering imported doors, the Philippine buyer should be able to answer “yes” to every relevant item:
There is no one size for every Philippine building. In TOF Door’s Philippine steel-door experience, 800 × 2100 mm and 900 × 2100 mm are recurring nominal single-door sizes. Public local listings also show these dimensions. The final size must follow the project opening, approved drawings and applicable requirements.
Yes, it is commercially common and appears in Philippine retail listings. It is still necessary to confirm whether the listing refers to the leaf, panel, door set or another nominal dimension.
For certain TOF decorative entrance-door frames with trim, an opening of approximately 820 × 2120 mm may be recommended. This is a product-specific installation practice, not a universal formula. The approved frame and installation drawing should control.
For economic and socialized housing covered by the revised BP 220 rules, the stated minimum clear main-door width is 800 mm. The same rules state 700 mm for service or bedroom doors and 600 mm for bathroom doors. These are minimum clear widths within that regulation’s scope, not universal factory order sizes.
No. The 2024 BP 344 rules define clear width between the fully open door face and the jamb. The leaf, frame, stop, hinges and opening angle affect the result. The designer must select a door-set size that delivers the required clear passage.
TOF commonly encounters 1500 × 2100 mm as a preliminary double-door reference and 1200 × 2100 mm for an unequal double or secondary-leaf configuration. The leaf split and clear opening must be confirmed on the drawing.
Not automatically. A fire door must match the approved opening, egress requirements and applicable test or listing evidence. Frame, leaf configuration, glazing, louvers and hardware can affect acceptance.
For complex projects, TOF may arrange paid on-site measurement after the service scope and logistics are confirmed. The service fee applies regardless of whether the subsequent supply order is awarded to TOF.
The most useful Philippine door-size references are not a substitute for project control. For retail and preliminary sourcing, 800 × 2100 mm and 900 × 2100 mm are recurring steel single-door dimensions, while 1200 × 2100 mm unequal double doors and 1500 × 2100 mm double doors are also relevant TOF Door commercial references.
Production, however, should never begin from a catalogue number alone. Importers and contractors must separate nominal size, leaf size, frame outside size, rough opening and clear passage. They must also confirm wall depth, finished floor, threshold, handing, installation and the applicable accessible or fire-safety requirements.
For a first import order, confirm every dimension and configuration in the approved drawing. For a multi-opening project, complete the door schedule and pre-production sample before releasing mass production.
Philippine buyers can contact TOF Door to request a size and configuration catalogue, review a door schedule, or discuss project measurement and customized door requirements.
