Rolls and cuts

Spoonflower prints all rolls of the same length identically, but doesn't say where in the pattern they start, or whether rolls of different lengths start at the same point. So the plan uses a single roll length: every roll matches the others and the cuts above stay valid. The pattern position at the ceiling may differ slightly from the drawing.

Roll lengths compared

Before you order

This plan is an estimate, not a guarantee. Measure each wall, rounding up to the next inch, and compare with the calculator on the design's Spoonflower page before ordering: it uses Spoonflower's own data for the design.

The plan assumes each panel covers 24″ of wall (rolls are printed about ½″ wider for the overlap), the trim allowances you entered, and the roll lengths offered for the wallpaper type you picked. It doesn't count the extra 1 or 2″ Spoonflower adds to each roll. Spoonflower prints all rolls of the same length identically but doesn't say where in the pattern they start, so the plan uses a single roll length. Half-drop panels are offset by hand when hanging.

Prices are Spoonflower's US prices per roll in November 2026, without promotions, shipping or taxes. They can change: check the price on Spoonflower before ordering.

Walls are rarely square, so keep the spare roll. Order every roll at the same time: each order is printed separately and colours can vary between orders. Spoonflower wallpaper is printed on demand, so extra rolls can't be returned. PatternShow isn't responsible for shortages or overages: you are responsible for the quantities you order.

How many rolls of Spoonflower wallpaper do I need?

Spoonflower wallpaper comes in rolls 24″ (61 cm) wide, so a wall needs one roll width, or panel, for every 24″ of its width, rounded up. Each panel must be as tall as the wall plus a few inches to trim at the ceiling and the baseboard, and long enough to line the pattern up with the panel next to it. Short pieces above doors and below windows can often come from the leftovers of longer rolls. The planner above works all of this out for the design you pick.

Why do half-drop designs need more wallpaper?

In a half-drop pattern, every other column of motifs is shifted down by half the vertical repeat. When a panel holds an odd number of columns, every other panel has to start half a repeat lower to line up with its neighbours, and that length is cut off and lost. When it holds an even number, every panel is identical and hangs like a straight match. The planner marks the panels to shift with ↓ and counts the extra length.

Why does the plan use a single roll length?

Spoonflower sells rolls of 3, 6, 9 and 12 feet (and 27 feet for some types) and prints every roll of the same length identically. It doesn't say whether rolls of different lengths start at the same point in the pattern, so mixing lengths could put panels out of step. The planner compares each length with Spoonflower's prices and picks the cheapest.

Order everything at once

Each Spoonflower order is printed on demand, and colours can vary slightly between orders. Order all the rolls for a wall, plus a spare roll, at the same time.
