How to Measure for Sheet Metal Hinges?

The core steps of measuring sheet metal hinges include: familiarizing yourself with hinge dimensions, measuring the door dimensions, and choosing the right hinge size. ‌

First, it is very important to familiarize yourself with hinge dimensions. Hinge dimensions need to be measured from top to bottom and from side to side, paying special attention to whether the hinge corners are square or radiused, which will affect the accuracy of the measurement‌.

Next, measure the door dimensions. For standard doors, you can use a tape measure to measure the width and height. The width is measured in the middle of the door, and the height is measured from the top to the bottom. The thickness and opening of the door also need to be measured, and these data will help choose the right hinge size‌.

Finally, choose the right hinge size. Generally speaking, as the thickness and width of the door increase, the size of the hinge also needs to increase accordingly. For example, when the door is 1 3/8" thick, the hinge height should be 3½"; when the door is about ¾" thick, the hinge height increases to 4"‌1. The installation location is also important, and the bottom hinge is usually 10 inches from the floor, and the upper hinge is 5 inches from the top edge of the door frame‌.
