To measure for a Custom Balcony Curtain, record three main dimensions: the area width, the required curtain height, and the mounting position. Measure the width at the top, middle, and bottom of the balcony opening, then use the smallest measurement if the curtain must fit inside the opening. Measure height from the actual track, rod, or profile location to the desired bottom edge, and clearly note whether your dimensions are finished sizes or opening sizes. I recommend taking each measurement in millimeters and checking the results at least twice before requesting a quotation.

Before using a tape measure, decide what the curtain needs to cover and how it will operate. A balcony curtain may be installed across an open balcony, inside a framed enclosure, around a corner, or beneath an existing roof or ceiling. These conditions affect the measuring points, the mounting hardware, and the amount of fabric or curtain material required. A supplier cannot reliably calculate a finished product from a single width measurement without knowing the installation layout.
First, identify whether you need coverage for privacy, shade, wind reduction, visual separation, or a combination of these functions. Then determine whether the curtain will slide horizontally, roll vertically, fold, or remain fixed. I also suggest photographing the balcony from several angles, including the ceiling, side walls, floor, railing, and any obstructions. Clear photos help a manufacturer review practical details that numbers alone may not show.
Look for beams, columns, glass panels, railings, drainage points, lights, air-conditioning units, doors, and opening windows. Mark the intended curtain line and check whether it will be mounted to a ceiling, wall, railing, or custom support profile. The curtain should not block required access or interfere with moving doors and windows. If the balcony has more than one section, measure each section separately rather than treating the whole area as one opening.
For a corner balcony, note whether the curtain should stop at the corner or continue around it. A continuous corner installation may need a special track arrangement, additional support, or separate panels. If the balcony has an irregular shape, create a simple sketch and label every side in sequence. This sketch can reduce confusion during quotation and production confirmation.
Measure the usable width along the planned mounting line. Take one measurement at the top, one in the middle, and one at the bottom, because walls, frames, and balcony structures may not be perfectly parallel. For an inside-fit curtain, the smallest width is usually the safer reference, subject to the supplier’s recommended clearance. For an outside-fit curtain, measure the full area that must be covered and add the required side overlap according to the installation design.
Do not automatically add fullness to the width yourself. Curtain fullness depends on the material, header style, panel construction, and operating method, so the supplier may calculate the finished fabric width differently from the opening width. Instead, provide the clear opening width and state whether you want one panel, two panels, or several sections. As a practical example, if the opening measures 2,400 mm at the top, 2,390 mm in the middle, and 2,410 mm at the bottom, record 2,390 mm as the narrowest clear width for an inside installation.
Measure from the exact mounting point to the desired bottom edge. If a track will be installed on the ceiling, measure from the ceiling or track reference line; if a rod or profile is attached to a wall, measure from that attachment line instead. Take height measurements at the left, center, and right sides of the opening. Use the shortest height for a fitted installation when the floor or balcony edge is uneven.
Decide whether the curtain should finish above the floor, align with a railing, or extend below a specific visual boundary. A small clearance may be needed to prevent dragging, especially on balconies exposed to water, dust, or debris. Do not assume a standard drop will work for every project. The final height should be confirmed with the fabric construction, hem, track, hooks, rollers, or other hanging components included.
Width and height are only part of the order information. Record the mounting method, such as ceiling-mounted, wall-mounted, railing-mounted, or installed inside an existing frame. Measure the available mounting surface and note whether it is concrete, metal, wood, glass, or another material. These details influence the selection of brackets, fasteners, profiles, and support spacing.

For projects using plastic profiles or custom curtain tracks, I recommend measuring the profile route separately from the curtain drop. Include straight sections, corners, returns, and any planned opening points. Huabao, as a supplier experienced in plastic profiles and custom curtain solutions, can review the profile layout together with the curtain dimensions so the proposed configuration is practical for production and installation.
Always label your measurements clearly. “Opening size” describes the physical area to be covered, while “finished curtain size” describes the completed curtain after allowances, hems, headers, or mounting components are considered. Mixing these two terms is one of the most common causes of quotation and installation problems. If you are unsure, submit the raw site measurements and ask the supplier to confirm the recommended finished dimensions.
A wide balcony may be easier to operate with two or more panels rather than one large panel. Panel divisions can affect the number of tracks, overlaps, meeting points, and package dimensions. For a corner or multi-sided balcony, list every panel separately, such as Panel A: 2,390 mm wide by 2,500 mm high. This method gives the manufacturer a clearer basis for reviewing the layout.
Overlap is useful where panels meet, where a curtain returns to a side wall, or where light and visibility control are important. The correct amount varies with the curtain design and operating system, so I do not recommend applying an arbitrary allowance. Instead, identify the locations where gaps may occur and ask the supplier to propose the overlap based on the selected material and hardware. This is especially important for outdoor or semi-outdoor balconies exposed to changing wind conditions.
I also advise buyers not to estimate the curtain quantity from floor area alone. Balcony curtains are usually ordered according to linear width, finished height, panel layout, and mounting configuration. A project measuring 6,000 mm in total width may require three panels, two corner sections, or separate curtains for different operating zones. The surface area by itself does not explain how the product must be made or installed.
| Item | Information to Provide |
|---|---|
| Opening dimensions | Top, middle, and bottom width; left, center, and right height |
| Measurement unit | Millimeters, centimeters, or inches |
| Mounting method | Ceiling, wall, railing, frame, or existing track |
| Panel arrangement | One panel, two panels, multiple panels, or corner layout |
| Operating direction | Left opening, right opening, center opening, or fixed installation |
| Site conditions | Obstructions, uneven surfaces, drainage, wind exposure, and access requirements |
A useful order package should include a dimensioned sketch, site photographs, material preferences, color requirements, installation location, and the expected quantity. If the project includes several balconies, identify each area with a room or elevation name. I also recommend confirming whether the quotation includes profiles, tracks, brackets, fasteners, finishing, packaging, and installation guidance. These items can influence the total project cost and delivery arrangement.
At Huabao, I understand that buyers often need more than a fabric quotation. A custom balcony curtain may require coordinated dimensions for the curtain body, plastic profiles, mounting components, corner sections, and operating accessories. We can review your measurements, drawings, photographs, and application requirements before confirming a production proposal. When site information is incomplete, we use conservative assumptions and identify the points that require confirmation rather than presenting uncertain dimensions as final.
Our support can include dimensional review, material and color discussion, panel planning, plastic profile coordination, packaging requirements, and communication for export orders. The exact available options depend on the product structure, order quantity, tooling requirements, and destination. For a more accurate evaluation, send the opening measurements in one consistent unit together with the intended mounting method and balcony photos.
The most reliable way to measure for a Custom Balcony Curtain is to document the opening width, mounting height, installation method, panel layout, and site restrictions together. Measuring three width points and three height points provides a more dependable basis than taking one quick dimension, while a sketch and photographs help explain the real installation conditions. I recommend sending the raw measurements to the supplier for confirmation before production, particularly when the balcony is uneven, curved, corner-shaped, or exposed to outdoor conditions.
Your next step is to prepare a measurement sheet using millimeters, label every panel, and identify whether each number is an opening size or a finished-size request. Send this information to Huabao with photos and your preferred curtain function, material, color, and mounting solution. We can then help review the custom balcony curtain requirements and develop a practical quotation for your B2B project.
