Tool Usage

Return to old version

Set the window size, choose a fabric method, then generate usage and cost details.

The tool calculates by finished curtain rod or track width and supports two common purchase methods: fixed height by width, or fixed width by height. Load sample data first, then replace it with your own sizes.

Size settings

Enter the curtain rod or track width first. Fill in the finished height from the curtain top to the desired bottom position.

Common samples You can adjust manually after clicking

Window and installation size Decimals supported; enter centimeter values separately

Curtain rod/track width (m) If measuring only the opening, add left and right overlap first.

Finished height (m) Measure from the hanging point to the target curtain bottom.

Window type guide Used to generate measuring tips; does not force formula changes.

Total side overlap (cm) Enter when measuring window opening width; use 0 for track width.

Opening style Affects finished width per panel only; not total fabric.

Curtain layers Double layers estimate base fabric for both layers with the same settings.

Tip: For floor-to-ceiling windows, measure total track length. Leave about 1–3 cm off the floor to avoid dust.

Fabric parameters

Choose a purchase method first. Fixed height is common for 2.8 m-high fabric; fixed width is common for 1.4 m or 2.8 m fabric width.

Purchase method Different methods use different formulas

General settings Adjust to your actual process

Cutting waste (%)

Pattern repeat (cm) Enter 0 if no obvious pattern; enter pattern repeat if matching is needed.

Purchase rounding

Instructions

Software Usage Instructions

Set dimensions: Enter the curtain rod or track width and finished height, and select a window type reference such as floor-to-ceiling window, half window, bay window, or full-wall curtain.
Add installation parameters: Fill in the total left and right overlap based on actual measurements, choose single-opening or center-opening, and set single-layer curtains or fabric curtains plus sheer curtains.
Select purchase method:
- Fixed height, buy by width: Suitable for fabrics with fixed heights such as 2.8 m and 3.0 m. Estimate the purchase length based on the width after pleating.
- Fixed width, buy by height: Suitable for fabrics with fixed widths such as 1.4 m and 1.5 m. Estimate the purchase length based on the required number of panels and the cutting length per panel.
Adjust fabric parameters: Set the pleat multiplier, left and right hems, top and bottom hems, cutting loss, pattern repeat, purchase rounding, fabric unit price, and related costs.
Start calculation: After entering the “Calculation Results” step, click “Start Calculation” to view the recommended purchase quantity, fabric cost, estimated total cost, and number of finished panels or cut fabric widths.
View details: The results area displays the effective width, fabric width after pleating, number of widths, loss, rounding, and cost formulas for easy verification.
Save and output: Click “Save Settings” to keep the current parameters, or copy the calculation results or print them for quotations and purchase records.

FAQ

A: Fixed height, buy by width means the fabric height is fixed and you purchase based on the width needed for the curtain; fixed width, buy by height means the fabric width is fixed and you purchase based on the number of widths and the cutting length of each width. Confirm the fabric specifications before purchasing.

A: 1.5× is suitable for a simple look, 1.8× looks more natural, 2.0× is commonly used, and 2.2-2.5× gives a fuller effect. The multiplier can be increased appropriately for sheer curtains or lightweight fabrics, and reduced appropriately for heavy fabrics.

A: If a track or curtain rod has already been installed, it is recommended to enter the actual width of the track or curtain rod. If you only measure the window opening, enter the additional coverage needed in “Total left and right overlap”.

A: For the left and right hems combined, you can use 15-25 cm as a reference. For the top and bottom hems combined, you can use 10-30 cm as a reference. The actual value depends on the hanging method, bottom hem finish, and processing habits.

A: Pattern repeat is the spacing at which the pattern repeats. If there is a clear pattern and the pieces need to be joined and aligned, enter the pattern repeat distance. The tool will round each panel’s cutting length up according to the pattern repeat. If there is no obvious pattern, enter 0.

A: The tool calculates based on the fabric unit price, processing fee, estimated accessory materials, or other costs you enter. If you do not enter costs for installation, tracks, hooks, tiebacks, etc., these items will not be automatically included in the result.
