Calculators

Plan your quilt's size for a bed or a set of blocks

The Quilt size calculator answers three questions: how big a grid of blocks finishes, what size quilt covers a bed, and how many blocks fit a size you already have in mind.

Where to find it

Studio top bar → Calculators → Quilt size. Also at quiltler.com → Calculators, and in the Calculators tab of the iPhone and iPad app.

Open the quilt size calculator
On the Quilt size calculator, choosing Quilt size for a bed and a King mattress gives a quilt 106 by 95 inches, with a 15 inch drop on the sides and at the foot

How to do it

  1. Press Calculators in the studio's top bar and choose Quilt size. It opens on 6″ blocks, 5 across and 6 down, with the answer already in the You need card.
  2. Choose what to Work out: Finished size from blocks, Quilt size for a bed or How many blocks fit.
  3. For a bed, pick the Mattress and type the Drop (inches) over the sides and any Pillow tuck (inches).
  4. For blocks, type the Finished block (inches), sashing and border, and either the columns and rows or the target size.
  5. Read the card: the quilt's size, or how many blocks across and down.

Good to know

  • The drop is added on both sides and at the foot. A quilt that reaches the floor needs a bigger drop.
