Scale t-shirt artwork to its intended physical print size while keeping its proportions locked. For a raster image, check how many pixels remain at that size. For example, an image 3,000 pixels wide provides 300 pixels per inch at a width of 10 inches, or 250 pixels per inch at 12 inches.
Start with the garment and placement
Choose the shirt model and print location first. A chest design, a full front print, and a sleeve mark need different spaces. There is no single maximum print size for every garment and placement. Check the printable area in the design tool and confirm any uncertain dimensions before ordering.
For a mixed group order, review the smallest garment as well as the largest. Use the youth size comparison and, when relevant, the BELLA+CANVAS 3001 chart. Garment width is useful context but is not the same as its permitted print area.
Pixels, inches, and effective resolution
Divide pixel width by print width in inches to find effective pixels per inch (PPI). Check height the same way. Use the resolution requested for your production process; 300 PPI is a common working reference, not a guarantee that every file will print well.
| Image dimensions | Print size | Effective resolution |
|---|---|---|
| 3,000 × 3,600 pixels | 10 × 12 inches | 300 PPI |
| 3,000 × 3,600 pixels | 12 × 14.4 inches | 250 PPI |
| 1,200 × 1,200 pixels | 8 × 8 inches | 150 PPI |
| 2,400 × 3,000 pixels | 8 × 10 inches | 300 PPI |
These are mathematical examples, not approved print-area dimensions. Changing an image’s resolution label without adding real detail does not make a blurry source sharp.
Resize without stretching the design
- Keep a copy of the original artwork.
- Turn on the linked-width-and-height or lock-proportions option in your editor.
- Enter the intended print width. Let the editor calculate the height from the original aspect ratio.
- Check that both dimensions fit the selected print area. If not, reduce the design proportionally or revise the layout.
- Inspect small text, fine lines, and edges at the intended output size. Save the requested file format without repeatedly recompressing a low-quality original.
For instance, an 8-by-10-inch design enlarged to 12 inches wide becomes 15 inches tall. Setting it to 12 by 12 inches instead would distort it. To fit a 12-by-12-inch area without cropping, that design would be 9.6 by 12 inches.
Photoshop: check size without inventing pixels
In Image > Image Size, turn off Resample to inspect the relationship between the existing pixel count and the physical output size. Keep proportions linked. Adobe explains that resampling changes the pixel count; increasing it does not recreate missing original detail.
Vector artwork and a paper placement check
Vector paths can be resized without the pixel-grid limitation of a raster image, but embedded photographs still have a pixel count. Small lettering and thin strokes also need to remain printable. For a quick placement check, print a paper outline at actual size and position it on a comparable shirt. Disable “fit to page” and measure the output with a ruler. This checks scale and placement; it does not simulate the finished ink or fabric.
Upload your design in the ooShirts design tool and review its placement on the chosen garment. For a budget-sensitive order, compare print locations and colors using our affordable printing guide and an exact quote.
