Choosing the right door handle size can make all the difference. Not only does it influence the look and feel of your room, but it also affects functionality. Whether you're updating your home or installing new handles for the first time, getting the right size is essential for both comfort and aesthetics. This guide will explain everything you need to know to pick the perfect door handle size for your doors, along with expert recommendations from our range of premium handles.

1. Why Does Door Handle Size Matter?

At first glance, door handles might seem like a minor detail in your home design. But choosing the right size can improve both your door’s functionality and overall design. If your handle is too small for the door, it can feel out of place or difficult to use. Too large, and it might overwhelm the door's look or make the operation awkward.

Functionality: A properly sized handle ensures easy, comfortable use. If your handle is too small for a heavy door, you might struggle to open it. Likewise, a handle that's too large on a lightweight door may be impractical.
Proportional Aesthetics: The size of your handle plays a major role in the room's overall appearance. Choosing the right proportions ensures the handle complements the door's size, creating a balanced, cohesive look.

2. Standard Door Handle Sizes: What You Need to Know

To make sure you choose the best handle size, let’s look at the common sizes and when they are typically used. It all comes down to your door type – is it internal, external, or a specialty door? Each has its standard sizes.

Internal Door Handles

For internal doors (like bedrooms and bathrooms), handles typically fall into these ranges:

Lever Handles: Most interior lever handles measure between 100mm and 130mm in length. This is the sweet spot, ensuring the handle is large enough for comfort but not so large that it looks out of place.
Knobs: If you're opting for knobs, expect sizes between 30mm and 40mm in diameter. These are great for smaller doors or where you don’t need the larger grip of a lever.

External Door Handles

External doors often need more substantial handles for both visibility and security:

Lever Handles: For front or back doors, choose a lever handle between 120mm and 150mm in length. These handles allow for a firm grip and provide strength for secure operation.
Knobs: Knobs on exterior doors typically range from 40mm to 50mm in diameter. This size ensures a firm grasp while keeping the door’s look elegant.

Specialty Doors (Sliding, Bi-fold, or French Doors)

Specialty doors, like sliding or bi-fold, have their own handle size requirements:

Sliding Doors: Sliding door handles are generally 150mm to 300mm long. This provides smooth operation while ensuring the handle doesn’t overpower the door.
Bi-fold Doors: These often use handles in the 100mm to 150mm range, keeping the design compact and functional.
French Doors: French doors typically require larger, more decorative handles, ranging from 150mm to 200mm in length to complement their elegant style.

3. How to Measure Your Door Handles

Measuring for the right handle size is key to ensuring a perfect fit. Here’s a step-by-step guide to get your measurements just right:

Backset Measurement

The backset refers to the distance from the edge of the door to the centre of the handle. For most doors, the standard backset is 60mm or 70mm, though some models may vary. Ensure your handle is compatible with your door’s backset for a smooth fit.

Handle Length

For lever handles, expect lengths between 100mm and 150mm. For knobs, you’ll be measuring diameter, usually between 30mm and 50mm, depending on the door's size.

4. How to Choose the Right Size for Your Door

Now that you know how to measure, here’s how to choose the right size for your door:

For Standard Internal Doors: Opt for a lever handle between 100mm and 130mm or a knob with a 30mm to 40mm diameter.
For External Doors: Select a lever handle ranging from 120mm to 150mm, or a knob between 40mm and 50mm, depending on the door's function.
Consider Door Functionality: Larger, heavier doors need more substantial handles, while lighter doors can work well with smaller, simpler handles.
Match Proportions: Always keep the overall proportion of the door and room in mind. A small door with a large handle can look disproportionate, while a tiny knob on a large door can feel out of place.
