Standard Interior Door Sizes
Quick answer:
The standard interior door height is 210 cm, while width varies by room: 70–80 cm for bathrooms, 80–90 cm for bedrooms and kitchens, and 90–100 cm for majlis / living rooms. Keybab recommends starting from these standard sizes because they offer the best balance of movement, furniture access, and cost — and can manufacture any WPC door to a custom size when a project's opening differs.
Recommended Sizes by Keybab
| Room Type | Door Width | Door Height |
|---|---|---|
| Bathroom | 70 – 80 cm | 210 cm |
| Bedroom | 80 – 90 cm | 210 cm |
| Kids' room | 80 cm | 210 cm |
| Kitchen | 80 – 90 cm | 210 cm |
| Majlis / Living room | 90 – 100 cm | 210 or 240 cm |
| Laundry room | 70 – 80 cm | 210 cm |
| Storage room | 70 cm | 210 cm |
Keybab's recommendation: always start from the standard size — it suits the design, daily movement, and budget best. Deviate only when the opening or the nature of the project requires it.
Why Door Size Matters
- Easier daily movement in and out.
- Moving furniture and appliances without difficulty.
- A consistent, well-proportioned interior design.
- Compliance with modern building standards.
Custom Sizes? Keybab Manufactures to Your Measurements
Standard is the recommendation, not a limitation. Keybab has full flexibility to manufacture WPC doors to the actual opening size, whether larger or smaller than usual:
- Villas, apartments, and homes with non-standard openings.
- Hotels and commercial projects needing consistent sizing across dozens of doors.
- Schools, hospitals, and offices.
- Tall doors (240 cm and above) for majlis areas and main entrances.
- Custom color, finish, and swing direction alongside the size.
Send the opening measurements and the door is manufactured precisely for a clean fit — no on-site adjustments needed.
How to Measure a Door Opening
- Width of the opening.
- Height from the finished floor level.
- Wall thickness.
- Door swing direction.
Take measurements after flooring work is complete for the most accurate result.
Important: Your Measurement Is Preliminary
When measurements are taken by the project owner, they should always be treated as preliminary, not final. The final manufacturing measurement should be confirmed by the manufacturer's own supervisor.
A trained supervisor accounts for details that a first measurement often misses — wall and frame thickness, final floor level, out-of-square openings, and swing and installation clearances. This step guarantees dimensional accuracy and prevents costly manufacturing or installation errors.
Why WPC?
High resistance to water and humidity, no swelling or peeling, insect-resistant, low maintenance, and far better dimensional stability than traditional wooden doors — which makes WPC the best fit for bathrooms and kitchens in high-humidity climates.
