MyTattooStencilAccountCreateHow Do I Make Sure My Tattoo Stencil Prints at the Right Size?
Updated October 31, 2026
Print the stencil at Actual size or 100% scale, on the same paper size the file was made for (A4 file on A4 paper, Letter file on Letter paper), and measure a reference of known length on the printout before you transfer anything. Most "my stencil came out small" problems come from a print dialog that quietly shrinks the page to fit the printer's margins, which typically makes it about 94-97% of its real size (PrintReadyKit). On an 8 cm design, that is 2.4 to 4.8 mm lost, enough to throw off lettering or a piece sized to fit between two joints.
Why stencils print too small
A print dialog has a sizing option, and on many computers it isn't set to 100% by default:
- Fit / Fit to printable area / Scale to fit shrinks or enlarges the page to the area the printer can reach. Adobe describes Fit as reducing or enlarging each page "to fit the printable area of the currently selected paper size," while Actual size "prints without scaling" (Adobe).
- The setting can be remembered from a previous job. In an Adobe community thread, a user found Acrobat Reader reused the last scaling choice between sessions, and a 10 × 10 cm box printed at 95% because someone had chosen Fit earlier (Adobe Community).
- Browsers can pick Fit for you. PrintReadyKit reports that Chrome applies Fit to printable area on its own when a PDF page is larger than the printable area, and that Edge opens PDFs with it selected (PrintReadyKit).
- There is a second scaling control in the printer driver. Behind the Properties or Preferences button, drivers have their own fit or scaling option (Epson calls it Reduce/Enlarge, Brother calls it Scaling). If that one is still on "fit," setting the app to 100% doesn't help (PrintReadyKit).
Where to set 100% in common apps
| Where you print from | Setting to choose | Avoid |
|---|---|---|
| Adobe Acrobat or Reader | Page Sizing & Handling, then Size, then Actual size (or Custom Scale 100%) | Fit, Shrink oversized pages |
| Chrome or Edge | More settings, then Scale, then Custom: 100 (or Actual size where listed) | Fit to printable area, Fit to paper |
| macOS Preview | Show Details, then Scale 100%, with Scale to Fit unticked | Scale to Fit |
| Printer driver (Properties / Preferences) | The option that does no scaling (Off, Normal size, Actual size) | Fit to page, borderless |

Also turn off borderless printing, which enlarges the page slightly, and keep pages per sheet at 1. Print from a desktop PDF viewer rather than a phone preview or chat app.
A4 vs Letter: pick the paper you actually have
A4 is 210 × 297 mm and US Letter is 215.9 × 279.4 mm (PrintNook). They are close enough to mix up and different enough to cause problems:
- An A4 file on Letter paper at 100% loses about 17.6 mm off the page height. If you let the printer "fit" it instead, everything shrinks to about 94%.
- A Letter file on A4 paper loses about 5.9 mm off the width at 100%, or shrinks to about 97% when fitted.
Neither shrink is acceptable for a stencil, so export the file in the size that's in your printer tray. In the US and Canada that's usually Letter; most other countries use A4.
Measure before you transfer
Scaling errors are hard to see by eye, so always check with a ruler on a plain paper print first:
- Print one page on ordinary paper, not stencil paper.
- Measure something on the page whose real size you know, such as a calibration square or ruler printed on the sheet.
- If it's off, fix the setting and reprint. Don't correct a stencil by eye.
- Hold the plain print against the placement to confirm the size looks right on your body before you use transfer paper.
Our printable tattoo stencil maker builds this check in. You set the design width in centimeters, choose A4 (210 × 297 mm) or Letter (8.5 × 11 in), and the stencil PDF includes a 10 cm calibration square that should measure 100 mm, within 2 mm, when printed at actual size. It can also add a test page for ordinary paper. If you use a thermal stencil printer instead, there is a separate 80 mm roll setting (76 mm printable width) at 203 or 300 dpi.

If the square still measures wrong
- Smaller by roughly 3-6%: a Fit setting is still on somewhere. Check the app dialog, then the printer driver.
- Smaller by about 6%, with an A4 file on Letter paper (or the reverse): the paper sizes don't match. Export again in your paper size.
- Cut off at an edge: paper size mismatch, or the design sits in the printer's unprintable margin.
- Correct on plain paper but different on stencil paper: check that the paper type and size in the driver match the sheet in the tray.
A stencil only controls placement and size. A licensed tattoo artist can tell you whether fine detail and lettering will hold up at the size you picked.
