Tattoo Stencil Size & Print Calculator
Set an exact physical width or height in cm or inches, or calibrate the stencil from a known span. Then preview paper fit and export a true-size 1:1 PDF.

Exact physical size
Set the real size before you think about print scaling
Choose the scale source that matches what you actually know. If the stencil must be exactly 14 cm wide, set the overall width. If one span inside the artwork must be 8 cm, mark those two endpoints and calibrate from that known distance. Pixels alone do not establish absolute physical size, and a print-menu label such as Actual Size does not choose the tattoo dimensions for you.

Tiling preserves scale; it does not shrink to one page
If the stencil fits inside the printable area, the PDF uses one page. Larger stencils are divided into overlapping sheets at the same established physical scale. Each marked sheet carries both its page number and row/column position so the assembly order stays explicit after printing.
Print sleeves and back pieces at true sizeThe PDF fixes page geometry, not the printer
The exported PDF places the stencil at the physical dimensions established here and keeps that scale when it creates additional tiled pages. The printer, driver, browser, or mobile app is a separate stage and can still resize the document. A correct PDF therefore is necessary, but it is not proof that the sheet in your hand is still 1:1.
Diagnose a print that changed sizeBefore transfer
Verify the paper, not just the print dialog
A 100% or Actual Size label is useful when the print path exposes it, but the physical sheet is the final check. Use one repeatable check before a client-critical stencil.
Match the paper
Load the same A4, Letter, A3, or custom format selected for the PDF. A paper-size mismatch can trigger fitting or clipping before the stencil reaches paper.
Preserve document scale
When the print dialog exposes scaling, use the option that keeps the PDF at document scale. Avoid Fit, Fill, Scale to Fit, or borderless enlargement when they change the intended output.
Print one control copy
For a tiled stencil, print the first marked page before committing the whole set. Keep every later page on the same paper, printer, and settings.
Measure before transfer
The 50 mm calibration line must measure exactly 50 mm on paper. Also check one important stencil dimension when the placement is size-critical.
Desktop: Actual Size and Fit are different operations
In print software that exposes both controls, Actual Size means no page scaling while Fit can enlarge or reduce a PDF to the selected printable area. Match the paper first, then preserve document scale. If part of the page cannot physically print, solve the paper or margin problem instead of hiding it with Fit.
iPhone and iPad: let the calibration copy decide
Mobile print controls vary by app and printer. If a percentage or Actual Size control is not shown, do not compensate by resizing the artwork blindly. Match the paper, avoid fit, fill, crop, or borderless enlargement when those controls appear, print one marked page, and measure it. If the scale is wrong and the mobile path gives you no useful control, use a print path that does.
Print from iPhone step by stepWhy the design bounds matter
Photos and exported images often include white or transparent canvas around the stencil. The Crop to the stencil control tells the calculator which outer background to ignore when sizing. It can remove outside margins, but it does not recolor the stencil or turn opaque background pixels transparent. If no meaningful border exists, different modes may correctly produce the same preview.
Image resolution at the final print size
The same raster file carries fewer source pixels per physical inch as its print size increases. The calculator reports that effective source sampling so you can inspect fine lines at the intended size. Physical size also changes how close lines read. Use the Fine vs Normal vs Bold line-weight guide before committing the final PDF.
A4 and US Letter are not interchangeable
A4 measures 210 × 297 mm. US Letter measures 215.9 × 279.4 mm. Choose the same format in the calculator that will be loaded in the printer. Mixing the two can trigger fitting, clipping, or a changed physical scale later in the print path.
Margins and overlap solve different problems
Margins reserve space inside each selected sheet. They do not configure a printer's physical non-printable area. Overlap repeats a strip of the design between adjacent pages so a larger stencil can be aligned. Overlap affects multi-page layouts; it does not add size to the finished stencil.
