So you’ve found a free sewing pattern you love, but it’s not quite your size. Classic. Before you give up or attempt some Pinterest-hack guesswork, let’s talk about how to resize a pattern properly — even if you’re a beginner.
Whether the pattern only comes in one size or just doesn’t fit your exact measurements, this guide will walk you through your options. No fashion degree required.
Why Resizing Matters
Sewing patterns aren’t one-size-fits-all — and bodies aren’t either. Resizing (also called grading) lets you adjust a pattern so it actually fits you, not some generic measurement chart from 1997.
The good news? You don’t need fancy software or a professional pattern-making setup. You just need to know what method works for your project.
First, Check Before You Cut
Before you touch a printer or a pair of scissors, check the original pattern:
- Multi-size pattern? Many free patterns include multiple sizes. Look for a size chart or nested lines. You might just need to choose a different line.
- Measurements included? Some designers list finished garment measurements — always compare these to your own before resizing.
- Ease matters. If the pattern has a relaxed or oversized fit, you might not need to resize at all.
Option 1: Scale It Up or Down When Printing (Quick & Dirty Method)
If you’re only off by a size or two, scaling the pattern on your home printer can work — especially for simple items like tote bags or boxy tops.
- Use your printer’s settings to reduce or enlarge the pattern (e.g., print at 105% or 95%).
- Be careful — scaling changes everything, including darts, seam allowances, and proportions.
- Always print a test page and double-check the measurement box included on most patterns.
Best for: Small size tweaks, beginners, or patterns without complex shaping.
Option 2: Manual Pattern Grading (The Smart Way)
If you’re resizing more than one size or want an accurate fit, grading is your best bet. It sounds intense, but it just means you’re increasing or decreasing the pattern at key points (bust, waist, hips, etc.) while maintaining the shape.
Here’s how:
- Trace the original pattern onto paper — don’t cut your master.
- Mark your bust/waist/hip points on the pattern.
- Measure the difference between your size and the original.
- Distribute the change evenly across seams (e.g., if you need to add 2 inches total to the bust, add ½ inch at four seams).
- Redraw smooth lines between your new points.
Use a curved ruler or hip curve if you’ve got one — or just go slow with a pencil and trust your eye.
Best for: Garments with shaping or anyone between standard sizes.
Option 3: Slash and Spread
This one’s a classic. You literally cut the pattern apart at key points, spread or overlap the pieces to change the size, then tape it back together.
- Great for adjusting width or length (e.g., adding to a bust or lengthening sleeves).
- Works well when only part of the pattern needs adjusting.
Just make sure to keep the grainlines straight and blend the curves after rejoining.
A Few Pro Tips:
- Always make a calico (test version) first — especially when resizing. Use cheap fabric and test the fit before committing.
- Don’t forget seam allowances — if the pattern doesn’t include them, you’ll need to add your own after resizing.
- Write notes on your pattern pieces so you remember what changes you made. Your future self will thank you.
Final thoughts
Resizing a pattern might feel intimidating at first, but once you’ve done it once, it becomes just another tool in your sewing belt. Don’t be afraid to tweak, test, and try again — half the fun of sewing is making things fit your way.
And hey, if you totally mess it up? It’s just paper. You’ve got this.
