Contractor Pro Tips

Bookmark on your phone. All our calculators are mobile-friendly. Save your most-used tools to your home screen for instant on-site access.

Always measure the actual angle. Never assume corners are 90 degrees in renovation work. Use a digital angle finder, then input the real number.

Add 10-15% for trim waste. Cuts, defects, and mismatches happen. Our linear feet calculator includes waste factors — use them.
