How to Measure for Custom Shelves (Get It Right the First Time)
Getting the right measurements is the most important step when ordering custom shelves. Whether you're fitting a closet, pantry, or garage, accurate measurements mean your custom shelves slide in perfectly without a second trip to the tape measure. The good news is it's simple if you follow a few basic rules.
In this short guide, we'll walk you through exactly how to measure your space so your custom shelves fit perfectly the first time.

## What You'll Need Before Measuring for Custom Shelves
- A tape measure
- A pen or pencil
- A notepad or your phone
- (Optional) A small level
---
## 1. Measure the Length (Left to Right)
1. Measure the distance from the left wall to the right wall where your custom shelf will sit.
2. Take this measurement in three places:
- Front
- Middle
- Back
Walls are rarely perfectly straight. Using three points helps you see if one side is tighter than the others.
Tip: Write down all three numbers and use the smallest as your "max safe length."

## 2. Leave a Little Clearance
If you make the custom shelf exactly the same length as the tightest spot, it may be hard to slide in. For most closets and pantries, we recommend subtracting 1/16" to 1/8" from your smallest measurement.
Example:
- Front: 36 1/8"
- Middle: 36 1/16"
- Back: 36"
Use 36" as your base, then order your custom shelf at 35 7/8" for an easier fit.

## 3. Measure the Depth (Front to Back)
Measure the distance from the back wall to the front edge where you want the shelf to stop. Common depths for custom shelves by room:
- Closet shelves above hanging clothes: 12"–16"
- Pantry shelves: 12"–18"
- Garage storage: 14"–20"+ depending on what you store
You don't usually need clearance on the depth unless the shelf has to fit inside a cabinet.

## 4. Check for Obstacles
Before finalizing your size for custom shelves:
- Look for baseboards, trim, outlets or brackets that might be in the way
- If there's a closet system track or rail, measure inside that space
- Note if the walls bow or are out of square
If you see something unusual, take a quick photo — it's always better to double-check before ordering your custom shelves.

## 5. Write Your Final Shelf Size Clearly
For each custom shelf, write your final size as: Length x Depth
Examples:
- 35 7/8" L x 12" D
- 30" L x 14" D
- 48" L x 16" D
When you order from Shelfix, you'll enter these numbers directly so we can cut and edge band each custom shelf to your exact size.
