For Upload-Your-Own Designs
Image Guidelines
If you're uploading your own artwork to print on a desk mat, give us the best file you can — print quality is dictated by what you upload.
File format
- ✦ Accepted: JPG, PNG, WebP
- ✦ Maximum file size: 20 MB
- ✦ Color space: sRGB (CMYK files will be auto-converted, colours may shift slightly)
Resolution & aspect ratio
Your file is printed at 150–200 DPI. Recommended minimum resolutions by size:
| Size | Aspect | Min. resolution |
|---|---|---|
| Small (12×18″) | 3:2 | 2700 × 1800 px |
| Large (12×22″) | 11:6 | 3300 × 1800 px |
| XL (16×32″) | ≈ 2:1 | 4725 × 2325 px |
| XXL (18×36″) | 2:1 | 5400 × 2700 px |
Tips for the best print
- ✦ Bleed: leave a 0.5″ safe zone from each edge — anything closer may be trimmed
- ✦ Avoid pure black (#000) backgrounds — use #0a0510 or #1a1a1a for richer print
- ✦ Use bold, high-contrast colours — they pop on the polyester surface
- ✦ Test small text size at print scale before uploading — anything below 14pt may smudge
- ✦ Avoid heavy noise/grain — it compounds when scaled
