Enter your numbers in inches or millimeters and the result updates instantly in your browser, with no sign-up and no app to install. Use it on your phone at the bench, then copy or print the result for your cut list.
Measure the room; add 5–10% waste for straight lays and 15% for diagonal or herringbone.
