About

Indoor Project Planner helps homeowners and DIYers work out how much material to buy before they go to the store, and compare products on what they will really cost for their rooms, not just the price per square foot or per can.

How the planners are built

• Every formula is published on How we calculate.
• Every default (waste, overlap, rounding, standard sizes) is visible and can be changed.
• Calculations run in your browser. We do not store your measurements.
• Results are estimates. We always recommend checking the product label and your supplier.
