About Wallpaper Calculator
The Wallpaper Calculator helps you estimate exactly how many wallpaper rolls you need for your room. It accounts for room dimensions, doors, windows, and pattern matching waste to ensure you order the right amount.
Whether you're redecorating a single room or planning a full home renovation, this calculator prevents over-ordering (saving money) or under-ordering (avoiding color batch mismatch issues).
Our calculator uses standard Indian/European roll sizes (10m × 0.53m = 56.8 sq ft) and adjusts waste based on pattern repeat. It also provides cost estimates when you enter the price per roll.

Step 2: Enter the number of doors and windows (to subtract from wall area).
Step 3: Enter the pattern repeat in cm (0 for solid, 25-64cm for patterned).

Wallpaper Installation Tips
- 💡Order all rolls from the same batch: Different batches can have slight color variations. Order all your wallpaper at once to ensure color consistency.
- 💡Prepare walls properly: Clean, smooth, and prime walls before hanging wallpaper. Use a wallpaper primer/sealer for best results.
- 💡Buy extra for repairs: Keep at least 1 extra roll for future repairs (stains, damage, or future touch-ups).
- 💡Check pattern match type: Different patterns require different matching methods. Read the instructions carefully before starting.
- 💡Allow for drying time: Don't rush the installation. Allow proper drying time between hanging and trimming for best results.
