To make a wall stencil, you settle on a size, print the design large, turn the print into something sturdy, then cut it and paint through it one section at a time. The printing is the part most guides skip, and it is where a large stencil goes crooked.
We read the code behind our free Stencil Maker on November 3, 2026, so the sizes and margins below describe the files it really produces. We have not painted a wall with one, so the painting advice comes from the people named in this guide, who did. Use your own images or designs you have the rights to, and get permission before you paint a wall you don't own.
The Print size option has three choices: 1 sheet, 2 × 2 sheets and 3 × 3 sheets. The PDF always uses US Letter pages. Here is what those choices give you, worked out from the code's page layout.
| Your image shape | 1 sheet | 2 × 2 sheets (4 pages) | 3 × 3 sheets (9 pages) |
|---|
| Square | 7.5 × 7.5 in | 15 × 15 in | 22.5 × 22.5 in |
| Upright 3:4 | 7.3 × 9.75 in | 14.6 × 19.5 in | 21.9 × 29.25 in |
| Wide 4:3 | 9.7 × 7.25 in | 19.3 × 14.5 in | 29 × 21.75 in |
So the largest tiled stencil is about 29 inches on its long side. That suits a feature above a bed, a motif you repeat or a door panel. It won't cover a wall in a single piece, which leaves you two choices for anything larger.
One is to repeat the motif, as the rest of this guide assumes. The other is to scale up the SVG in your own design software and take it to a print shop, since it is a vector file. MrKate's wall stencil project suggests a place like FedEx for an oversized print, and the Epbot project paid about $3 for a full-size print at Kinko's back in 2018. Expect a different price today.
Upload your image to the Stencil Maker. The preview runs in your browser and needs no account. The download needs a free account and uses no credits. You get a PNG, an SVG and the tiled PDF.
Choose the print size first, because it changes what you can safely cut. Bridges, the thin strips that hold floating pieces in place, measure about 1/160 of the long edge. Any shape smaller than about 1/90 of the long edge gets removed. Here is what that means for an upright 3:4 image:
| Finished long edge | Bridge width | Smallest shape kept |
|---|
| 9.75 in | about 1.5 mm | about 2.8 mm |
| 19.5 in | about 3.1 mm | about 5.5 mm |
| 29.25 in | about 4.6 mm | about 8.3 mm |
Keep Bridges on. For a wall, raise Smoothing toward Simple shapes, since every extra curve is something to cut by hand, and every tiny piece is something to tear. The tool bridges up to 400 islands per layer, largest first, so check small areas in the preview.
The PNG inside the PDF has 2,400 pixels on its long edge. Across 29.25 inches, that is about 82 pixels per inch, so edges may look slightly stepped up close. For a hand-cut stencil you can smooth that with your blade.
Open the PDF and print at 100%, sometimes called Actual size. Fit to page shrinks the sheets, so the finished size changes and the trim measurements below stop being right.
Here is how the file is laid out, which you will need when you trim:
- Each page has a printable box. The margins are 0.5 inch on the left, right and top, and 0.75 inch at the bottom, because a label sits there.
- The sheets don't overlap. The picture stops at the edge of the box and carries on at the same point on the next sheet.
- There are no crop marks. The only guide is a small gray label such as "row 1 / column 2" at the bottom of each sheet.
- If your image doesn't fill the grid, it is centered. A square image on 3 × 3 sheets is 22.5 inches tall in a 29.25-inch grid, so the top and bottom rows have about 3.4 inches of blank space.
- With layers, each layer gets its own full set. Three layers at 3 × 3 is 27 sheets, and the label says which layer it is.
If your printer loads A4, know that these PDF pages stay US Letter. Print one sheet at 100% and measure it before you print the rest, since the margins may land differently.
Because nothing overlaps, the trim has to be accurate. Use a ruler and a craft knife rather than scissors.
- Lay the sheets out by their row and column labels. Row 1 is the top of the image, and column 1 is the left.
- On each sheet, cut 0.5 inch from the left, right and top, and 0.75 inch from the bottom.
- Butt the edges together on a flat surface. Do the joins row by row, then join the rows.
- Tape the front lightly while you check the fit, since a white area has no visible edge to line up against. Follow a black shape across each join and make sure it doesn't jump.
- Tape the back along each seam.
Check one seam before you trim all nine sheets. If the art jumps there, the printer likely scaled the page.
Taped printer paper won't last on a wall, and paint will warp it. Here are three approaches from people who did it, in order of how long they last.
The Cut Out + Keep project is the quickest. It joined nine letter sheets on cheap roll paper and covered the back in wide clear packing tape, which stays thin and flexible. It was for a 24 × 36 inch canvas rather than a wall.
The Epbot project went further for a large wall. The author soaked a full-size print in clear lacquer on both sides, covered it with four layers of packing tape, and cut it out. They made two copies so one could dry while they used the other. They also wrote that skipping the edge sealing was a mistake, and that the stencil tore and needed patches.
MrKate traces the print onto a thin mylar sheet with a colored marker and cuts that with a craft knife on a mat. Plastic is tough to cut, so go slowly, but it is the one to choose for many repeats. Tape the plastic over your print so it doesn't move while you trace.
Both wall projects used a small foam roller, and Epbot's author offloaded nearly all the paint onto cardboard first, because extra paint bleeds under the stencil. That author also found bleeding common on textured walls, and touched up the lines with small brushes. Expect some of that if your wall has any texture.
To hold the stencil, Epbot used spray adhesive on the back, and MrKate used small pieces of tape. To repeat a motif, MrKate works down the wall, then moves across, stepping back often to check the rows. Leave room in the design for tape, and leave a gap for the wall's end, then trim a stencil to fit it.
Epbot's project is an honest guide to time. It took about 8 hours for one person, plus several hours of touch-ups. The author also warns that walls and ceilings are rarely straight, so check a level as you go, and keep partial pieces for last.
Choose 2 or 3 layers for more tones. Each layer gets its own sheets. Layer 1 holds only the darkest parts and the last layer holds the most area, so paint the last layer first in the lightest color.
The files carry no alignment marks, so mark your wall with light pencil or painter's tape before the first coat. Cut each layer's sheets with the same outer edges and line each stencil up to those marks.
If you are not ready to cut anything, try Photo to Line Art for an outline you can trace onto the wall.
Can I print a stencil across several pages?
Yes. Choose 2 × 2 or 3 × 3 sheets in the Stencil Maker and download the PDF. It is free with a free account. Print at 100%, trim the margins and tape the pages together.
About 21.9 × 29.25 inches for an upright 3:4 image on nine US Letter sheets. To go bigger, enlarge the SVG in design software or use a print shop.
Do the pages overlap so I can line them up?
No. The picture ends at each page's printable box, with no overlap or crop marks. You trim the margins and join the sheets edge to edge, using the row and column labels.
