Wallpaper Estimating App: Roll Count Per Room, Pattern Repeat Included

SiteScope calculates how many rolls of wallpaper a room needs, straight from a 3D scan. Set roll width, roll length, pattern repeat, and match type once in your catalog, add the paper to the room, and strips are cut to the tallest wall with repeat waste and openings handled. Fewer site trips, no spreadsheet. Free includes estimating with up to 10 materials. Unlimited materials and quote PDFs are on Pro.

Challenges We Solve for Wallpaper Contractors

Pattern-Match Waste

Ordering wrong quantities means pattern-mismatch mid-wall or costly leftover rolls. Measured walls and one roll count for the room take out the guesswork.

Pattern Repeat Miscalculated

Calculating repeat waste by hand, strip by strip and match type by match type, is where most estimating errors happen. SiteScope factors straight, half-drop, and quarter-drop repeats into the room's roll count automatically.

Designer to Installer Handoff Friction

Designers specify wallpaper, installers buy it, and they're working from different numbers. A shared takeoff CSV closes that gap.

Features Built for Wallpaper Work

LiDAR 3D Scan*

Scan a room and get every wall's exact dimensions, length, height, net area, automatically. Learn more →

Pick the Walls You Paper

Every wall in the room is on by default. Switch off the walls you are not papering, and doors and windows come out of the area automatically.

Wall Elevation View

Stand any wall up in a flat elevation and see the exact shape and openings you're papering.

CSV Takeoff with Roll Count

Export a line-item summary with square feet, roll count, cost, charge, and margin, ready to paste into your proposal or send to the installer.

* 3D room scanning requires iPhone 12 Pro or later, or iPad Pro (2020 or later) with LiDAR sensor, on iOS 17 or later

Measurements Start with a 3D Scan

Walk through any room with your iPhone or iPad Pro's LiDAR sensor and a floor plan generates automatically, capturing every wall's exact length and height in minutes. Those dimensions drive the roll count.

Roll-Based Calculation

Enter Roll Specs Once, SiteScope Handles the Math

Set roll width, roll length, and pattern repeat in the material catalog. Pick a match type (straight, half-drop, quarter-drop) and SiteScope factors the repeat waste into the room's roll count automatically.

  • Roll width + length drive the coverage calculation
  • Strips cut to the room's tallest wall, repeat waste based on match type
  • Cost and charge per roll, margin calculated live
  • Reuse across rooms and projects, set up once

Capture, Model, Estimate: Roll Count in One Visit

Here's how wallpaper contractors and designers use SiteScope to send a quote PDF the same day they walk the site:

  1. 1 Capture. Scan each room. The floor plan is generated with every wall dimension
  2. 2 Review. Open the room on the Estimate page. Every wall is on; switch off the ones you are not papering
  3. 3 Estimate. Add the wallpaper. Rolls are counted for the whole room, cut to the tallest wall, with pattern repeat waste included
  4. 4 Send. Export roll count and square feet to CSV, or send a branded quote PDF

Roll Count, Not Guesswork.

Set your roll specs once: roll width, roll length, and pattern repeat. SiteScope calculates how many rolls the room needs. Free includes estimating with up to 10 materials. Unlimited materials and quote PDFs are on Pro.

  • Pattern repeat built in: choose straight, half-drop, or quarter-drop match type and the repeat waste is factored into the room's roll count automatically.
  • Cut to the tallest wall: strips are cut to the room's tallest wall, and rolls are counted once for the room, not wall by wall.
  • Wall elevation view: stand any wall up flat to see its exact dimensions and openings.
  • Export roll count, square feet, cost, and margin to CSV and drop it straight into your order form or client proposal.

Frequently Asked Questions

How many rolls of wallpaper do I need?
Measure each wall's width and height, total the area, then divide by the usable coverage per roll. Pattern repeat forces longer cuts so it raises the count, and most installers add a 10 to 15 percent buffer for cut errors and dye-lot reserve. SiteScope does this for the whole room once you add a wallpaper: strips are cut to the tallest wall, and the rolls are counted for the room.
How does pattern repeat affect how much wallpaper to buy?
Each strip has to start at the same point in the pattern so seams line up, which means strips are cut longer than the wall height. A straight match wastes the least; half-drop and quarter-drop matches need more because the pattern shifts across strips. SiteScope factors the match type into the room's roll count.
Does SiteScope deduct doors and windows from the takeoff?
Yes. Doors and windows are mapped to their exact positions on each wall and taken out of the net area. It also flags pattern repeats that fall entirely behind an opening as potential savings.
What is a wallpaper cut sheet?
A printable PDF for the installer with the kill point, a per-strip cut table, per-wall elevation thumbnails, roll inventory with a dye-lot warning, and a QC checklist. One PDF per room. See the cut sheets page for a full example.
Do I need an iPhone to use SiteScope for wallpaper?
A LiDAR scan needs an iPhone 12 Pro or later or an iPad Pro, on iOS 17 or later, but you do not have to scan. You can trace from a photo or blueprint, or build a floor plan from scratch, and still get a roll count for the room.
