Measure replacement screen mesh before cutting
Record the reference edges, quantity and extra material for every frame.
Open Screen Mesh Cut Planner →Measure the frame you have
This tool starts with dimensions you supply; it does not determine a frame size from an empty window opening. Lay a removable frame flat and check that it is square and usable. Record a name for each size, width, height and quantity. Note whether the measurements refer to the outside frame or the spline groove because the allowance instructions may use a specific reference.
Keep manufacturer methods separate
Phifer’s window installation guide describes laying mesh over the frame with a half-inch overlap on every side. The linked ADFORS sheet describes at least two inches past the spline groove on all four sides. Those are different methods and reference edges. Select the applicable preset or enter your own allowance after reading your product’s instructions. The tool does not turn these methods into one universal specification.
Check the cut result
For a 28 × 46 inch measurement and a half-inch allowance on each side, the cut is 29 × 47 inches. Width grows by one inch and height grows by one inch. Review all cuts before buying material, especially door screens and specialty products with their own instructions. The calculator estimates mesh and spline quantities; it does not select a compatible spline diameter or assess a frame’s structural condition.
