Painting: The average 12×12 ft room requires 1–2 gallons of paint for two coats. Always account for doors and windows, and don't forget the ceiling if you're painting it too.
Flooring: Order 5–10% extra flooring to account for cuts, waste, and future repairs. Our calculator automatically adds a 10% waste margin for you.
Concrete: Concrete is typically ordered by the cubic yard. Our calculator converts your dimensions and adds a buffer for spillage and uneven subgrade.
Wallpaper: Pattern repeat can significantly affect how many rolls you need. Our calculator accounts for this — just enter your wallpaper's pattern repeat value from the label.
