How it Works
1. Calculate Wall Area (perimeter x height).
2. Subtract openings.
3. Divide by usable roll coverage (typically 25-27 sq ft per single roll).
4. Adjust for Pattern Repeat.

FAQ
Single vs Double roll?
US wallpaper is often priced by single roll but sold in double rolls.
Pattern match?
Large repeats create more waste (up to 20%).
Usable yield?
A standard roll covers ~25 sq ft effectively.
Dye lot?
Batch number ensuring color consistency.
Primer?
Always prime walls for better adhesion/removal.
👷 Safety First: Always adhere to local building codes and regulations. Wear appropriate Personal Protective Equipment (PPE) when performing construction tasks.
