Understanding Wallpaper Calculations
Calculating wallpaper accurately is essential to avoid running out mid-project or having excessive leftovers. The key factors are your wall dimensions, the wallpaper roll's dimensions, and crucially, the pattern repeat.
Pattern repeat refers to the vertical distance between one point on a pattern and the identical point directly below it. For patterns to align seamlessly across strips, you often need to cut off excess paper, which contributes to waste. Our calculator accounts for this by ensuring each strip is long enough to match the pattern at the top and bottom.
Tips for Wallpapering Success
- Measure Carefully: Measure your walls multiple times to ensure accuracy. Consider measuring each wall individually if your room isn't perfectly square.
- Account for Openings: For doors and windows, measure the area but still calculate full strips for the wall section. You'll trim around openings.
- Buy from the Same Batch: Always purchase all your rolls from the same dye lot to ensure consistent color.
- Prepare Your Walls: Ensure walls are clean, smooth, and primed for best adhesion and finish.
- Start in an Inconspicuous Corner: If your pattern doesn't perfectly meet at the end, start in a less visible area.
With careful planning and this calculator, your wallpapering project will be a breeze. Enjoy your beautifully transformed room!
