Quilt patterns can come in many sizes. But what if the size of the pattern isn't the size you want? Maybe you want a throw instead of a mini quilt or a baby quilt instead of a king size. To resize your pattern, you need to know the percentage to reduce or enlarge the blocks. Read below to learn three easy ways to get the percentage you need to resize your blocks and templates.
Below is the standard formula to get the percentage for reducing or enlarging.
- Measure the shortest length of the original block size? e.g. 6 inches
- What size do you want the new block to be? e.g. 8 inches
- Divide the new size by the original size, e.g. 8 ÷ 6 = 1.33.
- Move the decimal point two steps to the right to get your percentage = 133%.
- Enter 133% into the copy machine to enlarge your 6-inch block to an 8-inch block.
- Do the opposite of above.
- Divide the small size (e.g. 6") by the large size (e.g. 8") to get your reduction percentage, e.g. 6 ÷ 8 = 0.75 = 75% reduction.
Proportional Scales may look a bit intimidating at first but they're easy to use. You can buy a Proportional Scale especially for quilters HERE.
How to use a proportional scale:
- On the bottom wheel, find the original size of your block (e.g. 6"), [Fig 1].
- Line up this number with the new size (e.g. 8") on the top wheel, [Fig 1].
- In the window, you'll see the percentage of the reduction or enlargement you need to resize your block, [Fig 2].
