Why Source From Hotian?
Why Source Custom Size Windows from Hotian?
Direct Factory Manufacturer
Hotian owns and operates its production facility in Anhui, China — no trading company, no middleman. Every custom size window is designed, fabricated, assembled, and inspected in-house, giving you direct factory pricing and full control over specification changes without approval chains or markup layers.
Any Dimension Accepted
There is no fixed size matrix at Hotian. Standard, non-standard, oversized, and renovation retrofit dimensions are all manufactured using the same made-to-order process — with millimeter-level fabrication tolerance and no surcharge for dimensions outside catalogue ranges.
Full Material & Glass Range
Thermal-break aluminum, multi-chamber uPVC/vinyl, and composite frame systems are all available in custom sizes. Glass packages — double IGU, Low-E, argon, triple IGU, laminated, acoustic, and impact — are cut and sealed to your exact window dimension at production stage.
Competitive Factory-Direct Pricing
Pricing reflects direct factory cost — material, production, and quality control — without distributor margins or retail markups. Volume tiers are available for development and multi-family project orders. MOQ starts at 1 unit with no single-unit premium applied to custom dimensions.
Confirmed Lead Time
Standard custom size window orders are completed within 20 to 25 working days from dimension confirmation and deposit receipt. Mixed-type project orders covering multiple window types and sizes are coordinated across production lines with a confirmed project-specific lead time at order stage.
Complete Export & Shipping Support
Hotian’s export team handles documentation, reinforced packaging, freight coordination, and customs paperwork for international orders. Whether shipping to a single job site or coordinating phased deliveries across a development project, our logistics team manages the process from production sign-off to delivery confirmation.
Precision at Every Stage — From Dimension to Delivery
A custom size window is only as accurate as the process that produces it. At Hotian, every stage from dimension calculation and material preparation through frame fabrication, glass cutting, hardware fitting, and final inspection is controlled within our own facility — so the window that arrives on site matches the specification confirmed at order stage.

Frequently Asked Questions
Frequently Asked Questions About Custom Size Windows
What window dimensions can Hotian manufacture to custom size?
Hotian manufactures custom-size windows across the full product range — sliding, casement, single hung, double hung, picture, awning, and fixed window systems. Widths from 12 inches to oversized multi-panel configurations, heights from standard to above 84 inches, and non-standard rough opening dimensions in any combination are within our standard production capability. Dimensions outside these ranges are assessed individually by our engineering team.
Is there a size surcharge for non-standard window dimensions?n time?
No. Hotian does not apply a surcharge for custom or non-standard window dimensions. Every window we produce is made to order, so the unit price reflects the material and production cost of the specific window — not a premium for deviating from a catalogue size.
How do I specify my window 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 window size from your rough opening, accounting for frame thickness, clearance gaps, and hardware requirements for your window 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 windows above standard catalogue dimensions?
Yes. Custom window heights of 60 inches, 72 inches, 84 inches, and above are regularly produced at Hotian for high-ceiling residential interiors, hotel guest rooms, commercial façades, and architecturally specified openings. Custom-height windows receive engineering review to confirm frame reinforcement, hardware specification, and glass engineering are appropriate for the increased height and panel weight.
Are custom width windows available for oversized openings and feature glazing?
Yes. Custom-width single and multi-panel windows for large living areas, storefronts, office façades, and panoramic residential applications are available across sliding, casement, picture, and fixed window types. Custom widths are available in aluminum and uPVC frame materials without a minimum width premium or upper width restriction within the structural capability of each material type.
Can I order custom size windows for a full renovation project with multiple different opening dimensions?
Yes. Hotian regularly supplies renovation projects with custom-size window packages covering multiple different opening dimensions across several window types in a single order. A full window schedule listing each opening dimension, window type, material, finish, and hardware requirement can be submitted for project pricing and coordinated production scheduling.
What is the lead time for custom size window orders?
Standard custom-size window orders are completed within 20 to 25 working days from dimension confirmation and deposit receipt. Mixed-material project orders combining sliding, casement, and fixed windows in multiple custom dimensions are coordinated across production lines and confirmed at order stage with a project-specific lead time.
Can you match the custom size window dimensions to an existing window system already installed on the project?
Yes. If you have an existing window system on site and need a replacement or additional unit in the same dimensions, provide the measurements of the installed window and we fabricate a matching replacement. For sliding systems, track dimensions and panel configuration details should also be provided to confirm hardware compatibility.
What glass options are available for custom size windows?
Custom-size windows are available with double or triple insulated glass units (IGU), Low-E coated glass for energy efficiency, laminated safety glass, tempered glass, acoustic laminated glass, and decorative or tinted glass options. Glass type is specified at order stage and all panels are cut and sealed to your exact window dimensions.
What documentation is provided for custom size window orders on commercial and development projects?
Commercial and development project orders include full shop drawing documentation showing window dimensions, frame profiles, glass specifications, and hardware schedules for each line item in the order. Shop drawings are available for contractor submittal, developer procurement review, and architect specification sign-off before production commences.
