The Essential Guide to Measuring Your Door for a Perfect Fit


At FTH Solutions, we understand that precision is key in home improvements. Whether you’re gearing up for a renovation or installing a brand new door, accurate measurements are the cornerstone of a flawless fit. Follow our expert guide to measure your door like a pro.

Step 1: Width Measurement

The width is the door’s horizontal span. To measure it:

  • Stretch the tape measure from one side of the door to the other, at the top, middle, and bottom.
  • Record the measurements. If they differ, the widest measurement is your width.

Step 2: Height Measurement

The height is the door’s vertical length. To measure it:

  • Measure from the top to the bottom of the door at several points.
  • Use the longest measurement as your door’s height.

Step 3: Thickness Measurement

The thickness determines how the door fits into the frame. To measure it:

  • Measure the door’s edge with your tape measure.
  • Don’t forget to measure the door frame (jamb) for a compatible fit.

Pro Tips

  • For replacement doors, measure the door frame, not the door itself.
  • Embrace the “measure twice, cut once” philosophy to ensure accuracy.
  • Visual aids like online resources and video tutorials can offer additional guidance.

While these steps will guide you through measuring a door for a perfect fit, we highly recommend consulting with a professional to ensure the best results, especially if you’re unfamiliar with the process or if it’s part of a larger renovation project. A professional can provide valuable insights and help avoid any potential issues.

By following these steps and seeking professional advice, you’ll be well on your way to ensuring your new or replacement door from FTH Solutions fits perfectly, enhancing both functionality and design.
