Closet Door Setup: Sizes, Options & Installation Tips

Choosing the right closet door isn’t just about looks—it’s about proper fit, function, and maximizing space. Whether you’re designing a new walk-in or upgrading an older reach-in closet, understanding closet door sizes, configuration options, and installation tips can save time, money, and headaches.

Let’s break down everything you need to know to set up your closet doors the right way.

Understanding Closet Door Configurations

Closet doors come in a range of formats, and each is ideal for different types of spaces.

• Stylish and space-saving
• Excellent for modern or farmhouse interiors

Bypass Closet Doors

• Slide over each other in parallel tracks
• Perfect for reach-in closets

💡 Your configuration affects the look, functionality, and space available in the room.

Closet Door Sizes: Standard & Custom

One of the most important steps in choosing a closet door is understanding the proper size.

Standard Closet Door Sizes (U.S.)

• Width: 24”, 28”, 30”, 32”, and 36”
• Height: Most doors are 80” tall
• Double doors for wider openings range from 48” to 72” total

How to Measure Your Closet Door Opening

1. Measure the width from side to side at the top, middle, and bottom of the opening.
2. Measure the height on the left and right sides.
3. Use the smallest measurements to determine your final door size.

✏️ Always account for hardware clearance when choosing sliding or bifold systems.
