Kids Growth Ruler




I love to build DIY wood projects.

Before I created the Kid's Growth Ruler, we would measure and mark the kids heights inside the closet door. This is a much better option to see how fast they grow without having the pencil marks all over the doors. This is a very simple project to do for a beginner. You just need 1x6 board, stain, sharpie and adhesive numbers.


• 1x8x8' (x1)

Black Sharpie

1" Self Stick Numbers




Shop Paper Towels

Tools for this project

Tape Measure


Miter Saw

Step 1: Cut 1x6 Board

Take 1x6 board and cut it to 84” long. You could make this any length you want. I cut it at 84” because I wanted the board to be same elevation as the door. Than using a random orbital sander, sand the board on all sides.

Step 2: Pre-Stain and Stain

On a small project like this, instead of using a brush for staining, I just use Shop Paper Towels. I don’t have to clean the brushes. So first, Pre-stain the boards, then after 10 minutes, apply the Stain. Follow instruction on the can for both Pre-stain and Stain for best results.

Step 3: Measure and Mark

Next, pull a measuring tape and mark every inch on the board with a pencil. Then draw thick lines using oil based black sharpie over the pencil marks. To draw the lines straight I used a Construction Square as a guide. To make this look like an ruler, I made the lines three different lengths. Starting from 0 up, numbers 0, 12 have 2” long lines. Numbers 3, 6, and 9 have 1 ½” long lines. Numbers 1, 2, 4, 5, 7, 8, 10, 11 have 1” long lines.

Step 4: Apply Matte Polyurethane

Once you’re done with drawings the ruler lines, apply a coat of matte Polyurethane.Let it dry for few hours, then with a fine grit sand paper (300 and up) sand the board lightly. Wipe off the dust and then apply a second coat of Polyurethane.

Step 5: Tape on Adhesive Numbers

For the actual feet numbers I used 1" Self Stick Numbers that I had left over from cornhole scoreboard project.

Step 6: Attach Ruler to the Wall

Next determine what wall the ruler will be attached to. In my case I attached the board on the wall above the baseboard. The baseboard is 2 ½” tall, so I had to cut off 2 ½” of the board so that when someone stands on the floor, the ruler will be elevated correctly to give the right reading. Attach the board to the wall using 2 ½” wood screws. That's all; you're done with this Kids Growth Ruler.

I've made another Kids Growth Ruler for my sister but with a different board size and color.
