Check before you order a print: is this image sharp enough at that size, and how large can it go?
Meets 300 PPI
Meets a common 300 PPI target. Blur in the original, thin lines and small text still need review.
These are common practices from public guides, not universal specifications. Adjust for kids’ and larger garment sizes, and check the supplier template, available height and seams. The hat range comes from a logo guide that includes embroidery; pixel counts do not replace embroidery digitizing. The tote range is for flat cotton bags.
Click either width endpoint to fill the calculator. Image mode keeps proportions; print-size mode changes only the width, so enter the height separately. Scroll the table sideways on narrow screens.
| Placement | Width cm / in | Width pixels at 150 PPI | Width pixels at 300 PPI | Source / use width |
|---|---|---|---|---|
| Left chest | 6.35–12.7 cm / 2.5–5 in | 375–750 | 750–1500 | Printify |
| Full front | 25.4–30.48 cm / 10–12 in | 1500–1800 | 3000–3600 | Printify |
| Full back | 25.4–35.56 cm / 10–14 in | 1500–2100 | 3000–4200 | Printify |
| Short sleeve | 2.54–10.16 cm / 1–4 in | 150–600 | 300–1200 | Printify |
| Below back collar | 2.54–7.62 cm / 1–3 in | 150–450 | 300–900 | Printify |
| Hat front (structured cap) | 10.16–12.7 cm / 4–5 in | 600–750 | 1200–1500 | Printful |
| Flat cotton tote | 25.4–30.48 cm / 10–12 in | 1500–1800 | 3000–3600 | Kapa99 |
StoreCalc groups supplier advice into these bands. They are not an industry standard or a quality guarantee. 200 PPI is an intermediate comparison only.
| Effective PPI | What to do |
|---|---|
| ≥ 300 | Meets a common 300 PPI target. Blur in the original, thin lines and small text still need review. |
| 150 ≤ PPI < 300 | Usable for some apparel. For detail, close viewing or a supplier requiring 300, print smaller or use a better original. |
| < 150 | Below the cited suppliers’ recommended minimum. Jagged edges or blur are possible; find the original or print smaller. |
Printful / Transfer Express (2026-10-22)
| Width cm | Width in | Pixels at 150 PPI | Pixels at 300 PPI |
|---|---|---|---|
| 5 | 1.97 | 296 | 591 |
| 10 | 3.94 | 591 | 1182 |
| 15 | 5.91 | 886 | 1772 |
| 20 | 7.87 | 1182 | 2363 |
| 25 | 9.84 | 1477 | 2953 |
| 30 | 11.81 | 1772 | 3544 |
| 35 | 13.78 | 2067 | 4134 |
Example inputs, not supplier specifications: 4500 × 5400 px at 30 cm wide gives 36 cm high and effective PPI = 4500 ÷ (30 ÷ 2.54) = 381. Maximum size at 300 PPI: 38.1 × 45.72 cm; at 200: 57.15 × 68.58 cm; at 150: 76.2 × 91.44 cm. Conversely, a 30 × 36 cm print needs 1772 × 2126 / 2363 × 2835 / 3544 × 4252 px at 150 / 200 / 300 PPI.
The prompt includes numbers and requirements only. Add your product, process and supplier template after copying.
Not automatically. Changing the DPI tag adds no pixels. Resampling adds pixels but cannot restore missing original detail. AI may redraw text, lines or textures: compare with the original and order a sample.
True vector paths scale without a fixed pixel limit; embedded photos do not. If the supplier needs PNG, export at the final size and target PPI. Renaming a file SVG does not vectorize it. This tool reads raster dimensions only.
No universal value applies. Printful recommends at least 150 for DTG and 300 for DTFlex; for sublimation, 150 for simple shapes and 300 for detail or text. Transfer Express accepts 150 for digital transfers and recommends 300 or more. Follow the product template; thin lines and white ink need separate checks.
Use the original pixel dimensions, not the phone screen size. For example, 4032 × 3024 px gives about 34.14 × 25.60 cm at 300 PPI, or 68.28 × 51.21 cm at 150 PPI. Blur, compression and cropping still matter; use the original file.
Confirm the final canvas and artwork boundaries first. This tool does not trim transparent margins; after cropping, recalculate with the remaining pixels. Embroidery needs digitizing and stitch constraints, which PPI cannot assess.
No. The browser reads the file on your device to get pixel dimensions; manual entry is available if reading fails. Shared URLs contain numbers and options only, not images, file names or file contents.
