Wallpaper Roll Planner

Wallpaper Roll Planner is an offline Android tool for estimating wallpaper rolls, planning pattern matches, and inspecting optimized cut layouts before you buy or hang.

Plan rooms wall by wall, place doors, windows, and niches, then see how many rolls you need and how each roll should be cut.

What you can do:
• Create projects with rooms, walls, and positioned openings
• Set roll width, roll length, trim allowance, and waste contingency
• Choose no repeat, straight match, or half-drop pattern matching
• Get a live estimate of rolls, strips, cut length, and offcut
• Open an interactive roll cut plan with zoom and pan
• Optimize cuts around full-width openings when possible
• Work fully offline — no account, ads, or internet required
• Export and import JSON backups through the system file picker
• Switch metric/imperial units and light/dark/system themes

Built for DIYers, decorators, and anyone who wants a clearer material plan than simple area division.
