How to Prepare Your Design for Embroidery (Complete Guide)
07 Jun, 2026 · by Customanic Team
Embroidery is one of the most premium ways to personalize apparel — but it works very differently from regular printing. Instead of ink, your design is recreated entirely with thread, stitch by stitch. That means not every design translates perfectly, and a little preparation goes a long way toward getting a result you'll love.
This guide covers everything you need to know before uploading your design: size rules, color limits, file formats, what works and what doesn't — with clear examples for each.
Why Embroidery Designs Have Special Requirements
With regular print methods, the printer faithfully reproduces every pixel of your design onto the product. Embroidery machines work differently — they follow stitch paths. Fine gradients, thin lines, and photographic detail simply can't be recreated with thread. The good news is that with a few simple adjustments, almost any concept can be made embroidery-ready.
Accepted File Formats
Before anything else, make sure your file is in one of these supported formats:
PNG
Recommended — supports transparent backgrounds
Best choiceJPEG / JPG
Supported — no transparency
SupportedSVG
Supported for vector-based designs
SupportedPDF, PSD, AI, TIFF
Not supported — export as PNG/JPEG/SVG first
Not supportedSize Requirements
To make sure your design stitches cleanly and stays readable on the final product, follow these minimum size rules:
Minimum text height
0.25" (≈6.35 mm)
Minimum line thickness
0.05" (≈1.27 mm)
Shape thickness range
0.05" – 0.5" (≈1.27 – 12.7 mm)
Anything smaller than these limits may be automatically simplified or enlarged during the digitization process to ensure it stitches properly.
Pro tip: Use high-resolution files — at least 1200 × 675 px or 300 DPI — so the digitization software has the most detail to work with.
Color Rules
Do: Use solid, flat colors with strong contrast. You can include up to 6 thread colors per design.
Don't: Use gradients, color blends, or subtle shading — these effects can't be recreated with thread.
Embroidery works with a fixed palette of thread colors. When your design is processed, each color is automatically matched to the closest available thread shade. If your design uses colors outside this palette or more than 6 colors, they will be adjusted automatically during digitization — which can sometimes cause unexpected color shifts.
For the most accurate result, design using only the 15 supported thread colors listed below.
The 15 Available Thread Colors
| Color | Hex Code | Swatch |
|---|---|---|
| White | #FFFFFF | |
| Black | #000000 | |
| Grey | #96A1A8 | |
| Navy | #333366 | |
| Aqua/Teal | #3399FF | |
| Purple | #6B5294 | |
| Maroon | #680000 | |
| Red | #CC3333 | |
| Flamingo | #CC3366 | |
| Orange | #E25C27 | |
| Gold | #FFCC00 | |
| Old Gold | #A67843 | |
| Kiwi Green | #7BA35A | |
| Kelly Green | #01784E | |
| Royal | #005397 |
Remember: Only up to 6 colors can be used per design due to embroidery limitations.
How Are Colors Applied to Your Design?
For uploaded designs
Thread colors are assigned automatically. The system maps each color to the closest available thread shade. If your design uses more than 6 colors, or colors outside the palette, they'll be adjusted automatically.
For text embroidery
Thread colors are selected manually in the design tool. You choose from the available palette directly when setting up your product.
A Note on Color Accuracy
Because embroidery uses physical thread rather than ink, slight differences between your original design, the product preview, and the finished item are normal. The preview is a close approximation — the real embroidered product may vary slightly due to thread texture, stitch density, and the nature of the fabric.
Negative Space (Gaps Between Elements)
Do: Keep clear, visible separations between design elements.
Don't: Rely on tiny gaps or thin empty spaces to define details — these areas tend to fill in or merge together during stitching.
If parts of your design are meant to be separate, make sure there's enough breathing room between them.
Images & Illustrations
Do: Use simple shapes and bold outlines.
Don't: Upload photographs, complex illustrations, or thin repeating patterns — they don't translate well to thread.
The simpler the artwork, the better it stitches. Think bold logos, icons, and clean illustrations rather than detailed artwork or photos.
Text
Do: Use fonts that are at least 0.25" (≈6 mm) tall with medium-to-thick strokes. If your font is too thin, switch to a bolder version or add a thick outline (stroke).
Don't: Use very thin or small fonts — fine serifs and script styles often lose clarity once stitched.
When in doubt, bold is better. A thin, delicate font that looks beautiful on screen can become unreadable once it's stitched.
Line Thickness
Do: Keep all lines at least 0.05" (≈1.3 mm) thick.
Don't: Use extremely fine lines or distressed/textured effects — these tend to disappear or look uneven once embroidered.
Fine Details
Do: Simplify your artwork and remove small decorative elements.
Don't: Include intricate details that won't translate in thread — tiny flourishes, micro patterns, and fine decorative elements will be lost once stitched.
Backgrounds
Do: Upload your design with a transparent background.
Don't: Use solid, photographic, or patterned backgrounds — they interfere with the stitching area and can add unwanted color fills around your design.
Quick Checklist Before You Upload
Use this as a final check before submitting your embroidery design:
What Happens After You Upload?
Once your order is placed, your design goes through a process called digitization — where it's converted into a stitch file that embroidery machines can read. It's free of charge, and we handle everything on our end.
Depending on your design, we may reach out to you for a quick approval or a minor revision before production begins. It's a smooth process when your design follows the guidelines above.
Want to know what happens next?
Understand digitization timelines, status updates, and what to do if your design needs adjustments.
Following these guidelines means fewer delays, fewer adjustments, and a finished product that looks exactly the way you envisioned it. When in doubt, simpler is always better for embroidery.
