Product Features
Achieving dimensional accuracy in a custom-size door requires precision at every production stage — from the initial dimension calculation and material selection through frame fabrication, glass cutting, hardware specification, and final QC. The features built into every Hotian custom-size door ensure the door produced to your specified dimension arrives ready to install cleanly into your opening.
Why Source From Hotian?
Non-standard door dimensions create supply problems that standard manufacturers cannot solve. Hotian’s made-to-order production model means custom sizing is not an exception — it is the default. Every door we manufacture is built to the dimensions you specify, regardless of whether those dimensions appear in any standard catalogue.
No Standard Size Restrictions
Hotian does not manufacture to a fixed size matrix. Every door order begins with your specified dimensions. Interior doors from 18 inches wide, exterior doors up to 84 inches wide, panel heights up to 120 inches, and track system widths up to 240 inches for sliding and bifold configurations are all within our standard production capability — without special tooling charges or extended lead times.
Precision Fabrication to Rough Opening
Providing your exact rough opening dimensions allows our production team to calculate the correct door size accounting for frame thickness, clearance gaps, and hardware swing allowances for your specific door type. For renovation projects where the rough opening has been confirmed on site, we fabricate to a verified fit — eliminating the gap, shimming, and trim work that arises from sizing a door to a catalogue dimension rather than the actual opening.
Custom Height Without Structural Compromise
Custom door heights — commonly 7ft, 8ft, 9ft, and 10ft for high-ceiling residential and hotel projects — require frame reinforcement, hardware specification adjustments, and glass panel engineering that differs from standard-height production. Hotian’s engineering team assesses each custom-height order individually and specifies the correct frame profile, glass thickness, hinge load rating, and multi-point locking configuration for the height and weight of the door being produced.
Custom Width Across All Door Types
Narrow-width interior doors for retrofit applications, wide single-leaf entry doors for accessible design, and oversized commercial entries beyond 48 inches are all standard project types at Hotian. Custom widths are available across aluminum, uPVC, steel, and wood frame materials with no minimum width premium and no upper width restriction within the structural capability of each material type.
Consistent Quality Across Mixed Dimension Orders
Renovation and development projects frequently require multiple door types in multiple custom sizes within the same order. Hotian’s production scheduling coordinates custom interior, exterior, sliding, and entry doors with different dimensions across parallel production lines, delivering every door in the order to the same quality standard — regardless of whether the batch contains 5 identical units or 50 units in 20 different configurations.
Project Documentation for Custom Dimension Orders
Custom-size door orders for commercial and development projects include full shop drawing documentation showing door dimensions, frame profiles, glass specifications, and hardware schedules for each line item. Shop drawings are available for contractor submittal, developer procurement review, and architect specification sign-off before production commences, eliminating on-site dimension disputes after delivery.
Precision Manufacturing at Every Stage
Every custom-size door at Hotian is produced through a controlled manufacturing sequence — from dimension verification, material selection, and engineering review through frame fabrication, glass cutting, hardware specification, powder coating, and final dimensional QC inspection — ensuring every door arrives at your site built exactly to the dimensions you confirmed at order stage.
Custom Size Door Solutions for Every Project Type
Renovation projects are the most common source of custom door size requirements. Existing openings in older residential and commercial buildings rarely match current standard door dimensions — legacy frame sizes, non-standard ceiling heights, and structural openings that predate modern dimensional standards all produce rough openings that cannot be filled by a catalogue door. For renovation contractors, Hotian's made-to-order production means every non-standard opening on the project schedule gets a door built specifically for that opening — with no on-site modification, no filler trim, and no visible gap between door frame and rough opening.
uPVC and vinyl custom size doors are particularly suited to retrofit applications in coastal and high-humidity climates where the replacement door needs to match a legacy opening dimension precisely while delivering the thermal and weather performance improvement the renovation is designed to achieve.

Frequently Asked Questions
Find answers to common questions about Custom Size Doors, specifications, hardware options, and delivery arrangements.
What door dimensions can Hotian manufacture to custom size?
Hotian manufactures custom-size doors across the full product range — interior, exterior, entry, sliding, bifold, patio, barn, and French door systems. Interior door widths from 18 inches, exterior and entry door widths up to 84 inches, and panel heights up to 120 inches are within standard production capability. Sliding and bifold track system widths up to 240 inches are available. Dimensions outside these ranges are assessed individually by our engineering team.
Is there a size surcharge for non-standard door dimensions?
No. Hotian does not apply a surcharge for custom or non-standard door dimensions. Every door we produce is made to order, so the unit price reflects the material and production cost of the specific door — not a premium for deviating from a catalogue size.
How do I specify my door dimensions for a custom size order?
Provide your rough opening width and height as measured on site or from your construction drawings. Our team calculates the correct door size from your rough opening, accounting for frame thickness, clearance gaps, and hardware requirements for your door type. For renovation projects, on-site measurement of the confirmed rough opening is recommended before placing a custom-size order.
Can you manufacture custom height doors above standard 6ft 8in?
Yes. Custom door heights of 7ft, 8ft, 9ft, 10ft, and above are regularly produced at Hotian for high-ceiling residential interiors, hotel lobbies, commercial entries, and architecturally specified openings. Custom-height doors receive engineering review to confirm frame reinforcement, hardware specification, and glass engineering are appropriate for the increased height and door weight.
Are custom width doors available for accessibility and ADA-compliant projects?
Yes. Custom-width doors to achieve specific clear opening dimensions for accessible design and ADA-compliant projects are available across interior and exterior door types. Provide your required net clear opening width and our team calculates the correct door width factoring in hardware projection and frame thickness to confirm the clear opening specification is met.
Can I order custom size doors as pre-hung units with frames?
Yes. Custom-size doors are available as complete pre-hung systems with frame, hinges, and hardware pre-assembled. Pre-hung supply is available for interior and exterior door types and is particularly useful for multi-unit residential and hospitality fit-out projects where reducing on-site frame installation time is a schedule priority.
What is the lead time for custom size door orders?
Standard custom-size door orders are completed within 20 to 25 working days from dimension confirmation and deposit receipt. Mixed material project orders combining interior, exterior, and sliding doors in multiple custom dimensions are coordinated across production lines and confirmed at order stage with a project-specific lead time.
Can Hotian supply custom size doors for a full renovation project with multiple different opening dimensions?
Yes. Hotian regularly supplies renovation projects with custom-size door packages covering multiple different opening dimensions across several door types in a single order. A full door schedule listing each opening dimension, door type, material, finish, and hardware requirement can be submitted for project pricing and coordinated production scheduling.
Are custom frame depths available to match non-standard wall thicknesses?
Yes. Interior door frames are available in custom depths to match non-standard wall thicknesses common in renovation projects. Provide your confirmed wall thickness and the frame is fabricated to match — eliminating the extension jamb and casing workarounds that arise when standard-depth frames are applied to non-standard wall assemblies.
Do you supply custom size bifold doors for non-standard opening widths?
Yes. Bifold door systems in non-standard opening widths, custom panel counts, and custom heights are available in aluminum and uPVC profiles for both interior and exterior patio applications. Provide your opening width and we confirm the correct panel count and individual panel dimensions to achieve the best fold configuration for your opening.
Can you match the custom size door dimensions to an existing door system already installed on the project?
Yes. If you have an existing door system on site and need a replacement or additional unit in the same dimensions, provide the measurements of the installed door and we fabricate a matching replacement. For sliding and bifold systems, track dimensions and panel configuration details should also be provided to confirm hardware compatibility.
What documentation is provided for custom size door orders on commercial and development projects?
Commercial and development project orders include full shop drawing documentation showing door dimensions, frame profiles, glass specifications, and hardware schedules for each line item in the order. Shop drawings are available for contractor submittal and developer procurement review before production commences.
