Wallpaper adds texture, pattern, and personality to rooms. This calculator determines how many rolls you need, accounting for pattern repeat and waste from matching designs.
Standard wallpaper rolls cover 56 square feet, though European rolls may differ. Pattern repeat is the distance before the design repeats vertically. Larger repeats create more waste as you must match patterns at seams. Add 10% waste for small patterns, 15% for large repeats over 18 inches.
Measure walls and subtract large openings like windows and doors. For accent walls, measure only the featured wall. Order all rolls from the same batch as dye lots vary between production runs. Extra rolls from your batch are valuable for future repairs.
Wallpaper installation requires proper wall preparation. Fill holes, sand smooth, and apply primer-sealer. Use wallpaper-specific adhesive unless paper is pre-pasted. Match patterns carefully at seams and smooth out air bubbles with a smoothing tool from center outward.
Quick Tips
- Always order 10-15% extra materials for waste
- Check local building codes before starting
- Measure twice, cut once — verify all inputs
