Measure first
Enter real dimensions and openings instead of guessing from square footage alone.
Add waste
Most outdoor materials need extra allowance for cuts, breakage, slope, or irregular areas.
Plan the work
Use these estimates to compare options and discuss quantities with your supplier.
Choose the Right Calculator
Exterior envelope projects
Start with the siding, roofing, or exterior paint calculator when the project changes the outside shell of the home. These tools account for wall area, openings, roof pitch, waste, and finish coverage so your estimate is closer to how materials are sold.
Outdoor living and landscape projects
Use the deck, patio, fence, lawn, and landscaping calculators when you are planning usable outdoor space. They help estimate pavers, boards, rails, posts, soil, mulch, seed, and other materials before you price the job.
