Window Screen Mesh & Material Calculator

How to find your mesh cut size

1. Enter the outside frame width, height and allowance on each edge. Set the number of identical screens and read the cut instruction; no roll or cord measurement is needed.
2. For purchases, enable roll planning and enter usable width and optional length per roll. Review the grid; choose rotation explicitly only if the material permits it.
3. For retaining cord, enable its section and measure the groove centerline separately. Enter an optional package length for a feasible package count.
4. Copy or print cut sizes independently. Export the complete plan only after every enabled optional calculation is valid; a no-fit warning is a valid result.

What this calculator provides

• Exact per-edge allowance, metric and decimal-inch inputs, with retained physical measurements across unit changes.
• Complete-roll purchasing respects intact pieces and separate roll ends.
• Optional retaining-cord planning uses independently measured paths and uninterrupted cuts.
• Cut-only and complete-plan summaries share the current calculation, with selectable text if copying fails.

Useful projects

• Replace mesh in one existing rectangular window-screen frame without planning a stock purchase.
• Repeat one cut size for several identical screens and compare two explicit roll orientations.
• Check whether a labeled cord package can supply an uninterrupted length for each screen.

Measurement and stock planning guide

Measure the outside edges of the existing rectangular screen frame, not the window opening. Enter the per-edge allowance required by your mesh/frame instructions. It is added twice to each dimension.

Area is useful for material totals, but cannot prove a cut fits. Both width and length must contain one intact rectangle; pieces cannot bridge roll ends.

Check material direction and product instructions before rotating. Rotation is applied only when you choose it. The gap is between adjacent pieces and rows only, with none outside the layout or after the last piece or row.

Continuous-roll length assumes one continuous supply. Occupied length across stock rolls restarts the grid on each roll. Purchased length includes every complete roll, even fragmented unused ends. Unused area includes gaps, side strips and separate tails; it is not one reusable offcut.

Measure width and height separately along the centerline of the retaining groove. Do not reuse outside-frame or mesh-cut dimensions. This model uses one uninterrupted cut per screen; remnants cannot be joined. Check the manufacturer's joining, cord and groove requirements. Corners and stretching are not modeled.

Unit changes retain exact measurements behind rounded displays until you edit a field, even to the same displayed text.

Independently checked examples

Frame 600 × 900 mm, 25 mm on each edge: cut 650 × 950 mm. Five cuts on usable rolls 1,400 × 2,000 mm with 10 mm gaps need two rolls as entered: capacity four, then one on the final roll. Continuous length is 2,870 mm; occupied length across separate rolls is 2,860 mm.

Three 90 × 60 mm cuts on 100 × 100 mm stock with zero gap require three rolls. Each roll fits only one intact cut. Dividing 180 mm of continuous length by 100 mm would wrongly suggest two rolls.

Cord path 800 × 600 mm gives a 2,800 mm perimeter. Add 200 mm once per screen: three uninterrupted cuts of 3,000 mm total 9,000 mm. A 5,000 mm package yields one cut, so buy three packages; 6,000 mm remains distributed among packages.

Planning limits

This is a feasible uniform repeat grid, not a globally optimal layout. Different sizes need separate plans; adding their roll counts does not optimize shared stock.

Check the frame condition, measurements and product instructions. This plan does not guarantee installation fit, fall prevention, pet containment or security.

No extra installation mesh is included. Confirm that zero allowance is appropriate.
