Choosing the right door for your home is more important than you might think. Whether it’s an interior door for privacy or an entry door that makes the first impression, the size of the door can make all the difference in functionality and style. When it comes to standard door sizes, knowing the dimensions that work best for your space is key. In this guide, we’ll explore common door dimensions, how to measure for doors, and what you need to know to make the best choice for your home.
What Are the Standard Door Sizes?
When we talk about standard door sizes, we’re referring to the typical dimensions most manufacturers use for residential and commercial doors. These sizes are based on years of industry practice, ensuring compatibility with door frames, walls, and hardware.
Common Interior Door Sizes
Interior doors are generally smaller and lighter than exterior doors. The standard height for most interior doors is 80 inches (6 feet 8 inches). For width, interior doors commonly come in the following sizes:
- 24 inches
- 28 inches
- 30 inches
- 32 inches
- 36 inches
The most common interior door width is 32 inches, though smaller doors like 24 inches are often used for closets or pantries. The standard door thickness for interior doors is typically 1 3/8 inches.
Exterior Door Sizes
Exterior doors, or entry doors, are generally larger and thicker, offering more durability and security. The standard height for exterior doors is also 80 inches, though some can be as tall as 96 inches (8 feet), especially in modern homes. The typical widths for exterior doors include:
- 30 inches
- 32 inches
- 36 inches
Most homeowners prefer the 36-inch width for main entrances, as it provides ample space for moving furniture and allows for accessibility. Exterior doors are typically 1 3/4 inches thick to provide extra insulation and security.
Specialty and Custom Door Sizes
Not all doors fit the standard mold, and in certain cases, custom sizes are required. Whether you’re dealing with an older home or have specific design preferences, you might need to consider custom door sizing. Let’s look at a few popular specialty door types:
French Doors
French doors are often used to add elegance and allow more light to flow between rooms or to the outside. These doors typically come in pairs, each with a standard width of 30 to 36 inches, meaning the total width can range from 60 to 72 inches.
Sliding Doors
Sliding doors are commonly used for patios or closets. For patio doors, the standard size is 80 inches in height and 60 to 72 inches in width. For interior sliding doors, especially closet doors, widths can vary from 48 to 96 inches, depending on the size of the opening.
Bifold Doors
Often used for closets, bifold doors come in a variety of sizes. The most common sizes for bifold doors are 24 inches, 30 inches, and 36 inches in width, with heights generally at 80 inches.
How to Measure for a Door Replacement
If you’re replacing a door, it’s essential to measure correctly to ensure a proper fit. Here’s a step-by-step guide:
- Measure the height: Use a tape measure to determine the height from the floor to the top of the door frame.
- Measure the width: Measure across the width of the door frame, from one side to the other.
- Check the thickness: Standard interior doors are 1 3/8 inches thick, while exterior doors are typically 1 3/4 inches thick. Confirm the thickness of your current door to match your replacement.
If you have prehung doors, the door comes attached to its own frame, so you’ll need to account for the frame’s dimensions as well.
Choosing the Right Door for Your Home
When selecting a door, size is just one of the factors to consider. You’ll also want to think about materials, style, and functionality. Let’s break it down:
Functionality
Think about how the door will be used. For closet doors, bifold doors or sliding doors are popular choices due to their space-saving features. For bedrooms, a solid interior door in standard sizes will provide the privacy you need. For entry doors, a 36-inch width is ideal for accessibility and easy movement of furniture in and out of the house.
Materials
For interior doors, lightweight materials like hollow core wood or MDF are common, offering an affordable and easy-to-install option. On the other hand, exterior doors are typically made of materials like solid wood, steel, or fiberglass, designed to withstand weather conditions and provide security.
Style
Whether you’re looking for a sleek, modern design or a more traditional look, the style of your door should match the overall aesthetic of your home. French doors are perfect for those wanting to enhance the elegance of their space, while sliding doors offer a minimalist and functional style for modern homes.
