Window screen repair
Window screen mesh roll calculator
Enter the screen sizes and compare two mesh rolls. Each layout includes your chosen cutting allowance.
Screen measurements
Use the same measurement unit for frames and rolls. In inches, a 25 ft roll is 300 in long.
Cutting allowance
Follow the instructions for your actual frame and mesh. The manufacturer methods use different reference edges; the editable allowance is applied to your entered measurements.
Compare two roll sizes
Enter current prices in one currency. Taxes, shipping and tools are excluded.

Roll layout & materials
Measured cut listRectangles include the extra mesh on every edge. The layout uses a packing heuristic; it is not a guaranteed minimum-waste solution.
Cut dimensions
Guides
Measure replacement screen mesh before cutting
Record the reference edges, quantity and extra material for every frame.
Compare mesh roll widths for several screens
Use a cutting layout rather than total area alone to compare purchases.
Make a screen cutting list and spline estimate
Separate mesh cut dimensions, frame perimeter and the material you buy.
How the tool works
Each cut adds the allowance twice to width and height, once on each edge. A rectangle-packing heuristic arranges those cuts inside complete rolls, allowing rotation only when selected. Purchase cost is the number of rolls times your entered roll price. Spline length uses the entered frame perimeters plus the chosen reserve, so it is an estimate rather than a measured groove length.
