Pro Contractor Tips for USA Homeowners

📏 Understanding “Squares”

In the USA construction industry, siding is sold by the “Square”. One Square equals 100 square feet of coverage. Always round up your calculation to the next whole box or square.

🏗️ Why Calculate Waste?

Never buy exactly the square footage of your walls. You will lose material due to cuts around windows, doors, and corners. 10% is standard for simple walls; 15-20% is safer for Victorian or complex designs.

🛡️ Don’t Forget Accessories

This calculator covers the main “field” of the wall. You will also need to budget for Starter Strips, J-Channels, Corner Posts, and Undersill Trim to complete the job professionally.
