Create Template

The variety of fonts available on an ordinary computer opens up a world of options when you’re looking to make house numbers. Size the numbers five to six inches tall and print them out on a sheet of paper.

Cut Them Out

Use a utility blade to carefully cut the numbers from the paper.

Attach Templates

Use a spray adhesive on the backside of your numbers and adhere the tacky paper onto the cement board.

Cut Out the Numbers

Depending on your house numbers, you might find it helpful to rely on a variety of tools. The coping saw can be used to navigate the edge of the numbers, but a hole saw or jigsaw will come in handy for removing the center in numbers like 0, 4, 6, 8 and 9.

Cut Out the Numbers

When cutting cement board, always wear a respirator to avoid inhaling the cement-board dust and goggles to prevent it from getting in your eyes.

Sand the Edges

After all the numbers are cut, use a piece of fine-grade sandpaper to smooth out sharp edges and irregularities on the numbers.

Prime and Paint

Prime and paint the custom house numbers with exterior paint to seal and weatherproof them.

Attach Hooks

Using 1/4” screws wrapped in a piece of fine-gauge wire creates a flush hook that can be used for a variety of installations.


Consider how and where you are going to install your house numbers. If your house is set back from the street, choose to hang them on a roadside tree to make them more visible.
