By Ashley GarciaFebruary 13, 2026

The size of your main entrance door can significantly impact the aesthetics, functionality, and security of your home. Measuring door sizes in millimeters ensures precision and compatibility with your chosen door frame and hardware. Let's delve into the world of door sizes, focusing on the main entrance door, and explore the ideal dimensions for your home.

Before we dive into the specifics, it's crucial to understand that door sizes can vary greatly depending on the region, architectural style, and personal preferences. However, we'll provide a general guide to help you make an informed decision when selecting your main entrance door.

Standard Main Entrance Door Sizes

Across Europe, standard door sizes are typically measured in millimeters and fall into two categories: internal and external doors. For main entrance doors, which are external, the most common sizes are 825mm (width) x 1981mm (height) or 825mm x 2050mm, with a thickness of 40mm to 50mm.

These dimensions cater to the majority of door frames and ensure compatibility with standard door hardware, such as handles, locks, and hinges.

Width Considerations

When choosing the width of your main entrance door, consider the space available in your doorway and the traffic flow through your home. A width of 825mm is suitable for most homes, allowing for easy passage of people and furniture. However, if you have limited space or prefer a wider doorway, you can opt for a door width of up to 925mm or even 1025mm.

Wider doors can accommodate wheelchairs, strollers, or large pieces of furniture, but they may require additional structural support and could impact the overall aesthetic of your home.

Height Considerations

The height of your main entrance door is typically determined by the height of your doorway and the ceiling above it. Standard door heights range from 1981mm to 2050mm, which should accommodate most people and furniture. However, if you have high ceilings or prefer a grand entrance, you can opt for a taller door.

Taller doors can create a dramatic effect but may require additional modifications to your doorway and ceiling, as well as specialized hardware to support the increased weight.

Custom Main Entrance Door Sizes

If you can't find a standard door size that suits your needs, consider investing in a custom-made door. Custom doors can be tailored to your specific measurements, ensuring a perfect fit and enhancing the curb appeal of your home.

When ordering a custom door, provide the manufacturer with the exact measurements of your doorway, including the width, height, and thickness. This will help ensure that your custom door fits seamlessly into your home and functions correctly.

Custom Widths

Custom widths can range from as narrow as 600mm to as wide as 1200mm, allowing you to create a doorway that perfectly suits your space and needs. Wider doors can accommodate larger furniture or improve accessibility, while narrower doors can help create a cozy, intimate atmosphere.

By understanding the standard door sizes and considering your specific needs, you can choose a door that enhances the beauty and functionality of your home. So, measure twice and choose once, ensuring that your main entrance door is the perfect fit for your space.
