Baby Onesie Print Size: Chest Dimensions
An infant fine jersey bodysuit prints at 5.6 x 7 inches (1680 x 2100 px at 300 DPI). Here is why scaling down an adult design does not work.

- An infant fine jersey bodysuit prints at 5.6 x 7 inches (1680 x 2100 px at 300 DPI). Here is why scaling down an adult design does not work.
- Print area is 5.6 x 7 in — roughly a quarter of the area of an adult tee front.
- Rebuild, do not shrink. Type below about 14 pt at this size is hard to read and prints soft on jersey.
- Bodysuits curve. The chest area is small and rounded, so wide designs distort at the edges — compact, centred lockups work best.
Onesies are the blank where the scale-down instinct fails hardest. The print area is a fraction of an adult tee, and type that reads perfectly at adult size becomes illegible once it is reduced to fit a baby chest.
Every print position, measured
These are the actual print areas Printify produces for this product, not estimates. Pixel values are at 300 DPI, the resolution print files should be supplied at.
| Print position | Inches | Centimetres | Pixels @ 300 DPI |
|---|---|---|---|
| Front | 5.6 x 7 in | 14.2 x 17.8 cm | 1680 x 2100 px |
| Back | 5.6 x 7 in | 14.2 x 17.8 cm | 1680 x 2100 px |
Placement that survives the real product
- Print area is 5.6 x 7 in — roughly a quarter of the area of an adult tee front.
- Rebuild, do not shrink. Type below about 14 pt at this size is hard to read and prints soft on jersey.
- Bodysuits curve. The chest area is small and rounded, so wide designs distort at the edges — compact, centred lockups work best.
The rule that overrides every chart: print areas are the maximum, not the target. Filling the entire area is almost never the best-looking choice — most strong designs use 70–85% of the available width and sit slightly above the geometric centre, because that is where the eye expects them on a worn or photographed product.

Quick answers.
What size should a baby onesie design be?
5.6 x 7 inches at 300 DPI, which is 1680 x 2100 pixels.
Can I just scale down my adult t-shirt design?
Not directly. The area is roughly a quarter the size, so fine type and thin lines fall below what prints cleanly. Rebuild with heavier weights.
Do onesie sizes have different print areas?
The print area stays the same across the size range; the garment changes around it.
