Just enter the number of doors and their height — the calculator instantly shows your total hinge count. Simple, accurate, and built for cabinet makers, contractors, and DIY homeowners.

Choosing the right number of hinges for your cabinet doors can make a big difference in how smoothly they open and how long they last. Our Hinge Quantity Calculator was created to make that decision quick and stress-free. All you need to do is enter the number of doors and the height of each door — the calculator instantly tells you the total hinge count needed for your project.

Here’s the simple rule of thumb that the calculator follows:

• Doors up to 40″ usually need 2 hinges.
• Doors between 40″ and 60″ should have 3 hinges for added stability.
• Taller doors between 60″ and 80″ generally require 4 hinges to support the extra weight.
• Any door above 80″ should have 5 hinges to prevent sagging over time.
  

These guidelines are widely used by cabinet makers and installers, and they help ensure smooth operation and long-term durability. Whether you’re building kitchen cabinets, vanities, or custom furniture, this quick tool saves you time and prevents guesswork.

After calculating, you can explore our Hinges Collection to find the perfect fit for your project. Every hinge at Berta Store is selected for precision, strength, and ease of installation.
