How to Use the Calculator (Step-by-Step)

Step 1: Measure Your Wall Height

Use a tape measure and input the wall height in inches.
Example: 96 inches (for an 8-foot wall)

Step 2: Enter Cleat Height

This is the vertical height of each cleat. Most people use 1x4s, which are 3.5 inches tall.
Enter: 3.5

Step 3: Enter Vertical Spacing

This is the space you want between each cleat. For example, 2 inches of space gives you room for easy hanging or future expansion.
Enter: 2

Step 4: Click “Calculate Layout.”

You’ll instantly see:

• How many cleats can you fit
• How much vertical space will they cover
• The height of the top cleat

Pro Tips

• Start your bottom cleat a few inches off the floor.
• Use the total vertical coverage value to center the layout.
• For aesthetic symmetry, adjust spacing so cleats end at a logical top line (e.g., just under the ceiling or under a shelf).
