How tall is a door in Canada?

Whether you’re replacing a door or designing a new build, knowing your dimensions upfront saves time, money and hassle

A STANDARD DOOR in Canada typically stands 80 inches (6 feet 8 inches) tall, but that’s not the only size you’ll find. Door heights can vary, whether replacing a door in your home, designing a custom entryway, or meeting commercial building codes. Let’s break down the common sizes and what you need to consider.

1. Standard Door Heights in Canada

Interior Doors

Most interior doors in Canadian homes follow a simple rule: 80 inches tall and 30 to 36 inches wide. These are the sizes you’ll see in bedrooms, bathrooms, and hallways. If you have an older home, your doors might be shorter—sometimes as low as 78 inches.

Exterior Doors

Front and back doors (entrances) also stick to the 80-inch standard, but there’s more flexibility. Some homes, especially modern builds, feature 84-inch (7 feet) or 96-inch (8 feet) doors for a grander look. These taller options let in more light and create an open feel.

2. Why Do Door Heights Vary?

Ceiling Height Matters

If you’ve got 8-foot ceilings, an 80-inch door fits proportionally. For 9-foot ceilings, an 84-inch door makes more sense, keeping everything balanced.

Regional and Style Preferences

Some regions prefer taller doors for a modern aesthetic, while traditional homes often stick to the standard. Custom-built houses may have even taller entries for a dramatic effect.

3. Commercial and Public Building Standards

Minimum Door Height for Businesses

Commercial spaces follow stricter regulations. In most cases, doors must be at least 80 inches high, though accessible entryways sometimes require taller designs to meet universal accessibility standards.

Fire and Safety Regulations

Certain doors, like those in fire exits or high-traffic areas, must meet additional height and width requirements for safety. It’s always best to check local codes before making changes.

4. Oversized and Custom Doors

Do You Need a Taller Door?

If you’re going for a bold entryway or a more open feel, a 96-inch door might be a great choice. These are common in luxury homes and commercial buildings, making spaces feel larger and more inviting.

What to Consider Before Installing One

• Frame adjustments – Taller doors require custom frames and possibly a higher rough opening.
• Cost – Custom doors are more expensive than standard ones.
• Hardware – You might need a longer handle or upgraded hinges to support the weight.

Final Thoughts

While an 80-inch door is the standard for most homes in Canada, you are not stuck with that size. If you want something taller, plenty of options exist—as long as your space allows it. Whether you’re replacing a door or designing a new build, knowing your dimensions upfront saves time, money, and hassle.
