Why Are Door Hinges Not Evenly Spaced? 5 Reasons

Why Are Door Hinges Not Evenly Spaced? Have you ever taken a constructive look at your door hinges? You will discover that the door hinges are not equally spaced and seem to be at different heights. Although this might not be the case for every door hinge, there is a valid reason why door hinges not evenly spaced and are at different heights is a concern. 

One of the reasons door hinges are not evenly spaced is that doors can be heavy, so placing door hinges unevenly helps distribute the door’s weight to prevent sagging. The top hinge carries the majority of the weight; hence, it is placed closer to the top of the door where the stress is greatest. 

Door hinges are not evenly spaced for several reasons, primarily related to structural integrity, weight distribution, and functionality. Most doors do not follow conventional measurements, but the principle remains the same.  

Why Are Door Hinges Not Evenly Spaced And At Different Heights

This design choice, far from arbitrary, is rooted in the principles of physics and structural engineering. It plays a crucial role in maintaining the door’s durability and functionality.

Door hinges are unevenly spaced at different heights to provide a more sturdy hold at critical positions on the door. This uneven spacing ensures effective weight distribution, prevents warping, and aids in smooth operation while also considering aesthetic balance.

The exact placement varies depending on the door’s size and weight. Here are several reasons for your door hinge’s uneven spacing:

Here’s a breakdown of why this spacing is important:

Weight Distribution: Doors can be quite heavy, especially solid wood doors or metal doors. The placement of the hinges is designed to distribute this weight evenly to prevent sagging. The top hinge carries the majority of the weight; hence, it is placed closer to the top of the door where the stress is greatest.

Structural Integrity: The spacing of the hinges is aligned with the sturdiest parts of the door and the frame. For example, the top hinge is often placed below the top edge of the door where the frame is strongest, and the bottom hinge is placed above the lower edge for the same reason. This helps to maintain the door’s structural integrity.

Prevention of Warping and Twisting: Uneven spacing helps prevent the door from warping or twisting over time. Consistent pressure and weight distribution ensure the door remains straight and functional.

Functional Efficiency: The middle hinge (in a three-hinge setup) acts as a stabilizer and aids in the smooth operation of the door. It’s usually placed at the centre or slightly below the centre of the door for optimal efficiency.

Aesthetic Considerations: While functionality and structural integrity are paramount, the placement of hinges also considers aesthetic balance. The spacing is often done in a way that is visually pleasing and symmetrical in its own right, even if not evenly spaced.

Here’s how each hinge functions:

  • Top Hinge 

The top hinge stays seven inches from the top to hold the door at a gravitational point. It ensures that gravity does not rip your door apart at the seams. The top hinge is the first holding point for a sturdy grip. 

  • Bottom Hinge 

The bottom hinge stays within eleven inches of the door bottom to ensure that the top hinge does not overwork. The hinge bottom extension offsets the load spread from the door top and balances the remaining load to the bottom. 

  • Middle Hinge 

The middle hinges are always of equal measurement because they cushion the rest of the door load. If the central hinges are unequal, your door might start ripping from the angle with a more significant burden. 

Tips For Proper Hinge Placement

Here are some tips to follow or observe for good door hinge placement. 

  • Ensure you are measuring the door hinge placements in inches.
  • Make a mark with a pencil indicating your measuring point on the door. 
  • With your hinge on the door, mark the holes to determine where to screw or put nails.

  • Always measure your full door length first to determine the number of hinges your door will need. 
  • Always start with the top hinge, then the bottom hinge next when screwing or nailing. 
  • The middle hinges should be equal between the top and bottom hinges. 
  • Ensure that you nail or screw precisely to avoid splitting the door. 


Door hinges are an easily neglected part of a door, so it is essential to fix them right. Placing them unevenly will ensure that your door has a strong hold on the frame and swings efficiently.
