Ever downloaded a miniature pattern that was the wrong scale for your project? You're not alone. Whether it’s a furniture template that’s too big or a printable floor that’s too small, adjusting the scale is actually pretty straightforward once you know how.
Here’s how I handle it:
🧮 Step 1: Figure Out the Scale Change
You’ll need to know two things:
-
What scale the pattern currently is (say, 1:12)
-
What scale you want it to be (say, 1:24)
Then use this simple formula:
New size % = (New scale ÷ Original scale) × 100
So for 1:12 → 1:24:
(12 ÷ 24) × 100 = 50% → print the pattern at 50%
And for 1:24 → 1:12:
(24 ÷ 12) × 100 = 200% → print at 200%
You can use my free scale calculator tool here to do the math for you.
🖨️ Step 2: Resize Digitally or Physically
-
If you have a PDF or printable, use your printer settings to scale the document by the percentage you just calculated.
-
If you’re working from a physical copy, a photocopier with scaling options will do the job.
-
For SVG files or templates, programs like Inkscape or Illustrator let you input exact percentages or dimensions.
If you're not sure how to do this in Canva or Adobe Acrobat, I wrote a full walkthrough here:

📏 Tip: Always Measure After Printing
Most patterns have a “1-inch square” or similar guide on the page. Measure it after printing to double-check it came out at the right size. If it’s off, adjust and try again.
What About Grids?
If you’re working by hand and don’t have access to a printer or copier, the grid method still works. Just draw a grid over your pattern and redraw it square by square onto a larger or smaller grid. A bit more effort, but still effective.
That’s it! Once you get used to the math (or use the calculator above), resizing patterns gets much easier.
Do you resize patterns often? Or do you just try to find them in the right scale? Curious to hear how others handle this!
I wish you happy crafting!
Kind regards,

Hi, would this work if I wish to change the scale of an actual part, please? I've a model that is 1/35 scale and I want to scratchbuild some parts from it to 1/76 scale; it looks like it should!
Yes, absolutely: it works the same way! 😊 Just take the original scale (1/35) and divide it by the new one (1/76), which gives you about 46%. So you’d shrink your part to roughly 46% of its original size.
That said, when you’re scratch-building instead of resizing a flat pattern, you might need to make very thin parts slightly thicker so they don’t get too fragile. Otherwise, the method is exactly the same: just scale everything down by that percentage.
And if you are in doubt, feel free to use my scale convertor! https://tool.everythingverysmall.com/

Many thanks for the swift reply, Lizzy. That's just made a model, (slightly) easier for me!
@geggy5310 you're welcome, and good luck! If you have more questions along the way, feel free to ask!
