All About Door Hinges :: Hanging on a Hinge
You know I find myself ogling (door) hardware frequently. And this is especially true with commercial spaces. And I know, I know — we are “generally” a site dedicated to residential construction, but when Ginny, an expert with commercial hardware, offered this — All About Door Hinges. Much of it applies to the residential setting as well. Enjoy. ~jb
A hinge is probably the most versatile piece of hardware in the building industry.
The most common commercial hinge for a “standard” 3’0” x 7’0” x 1 ¾” wood door is a ball bearing 4 ½” x 4 ½” butt hinge in brushed chrome. Very basic but does the job. We no longer stock non ball bearing hinges as we learned during door installs the majority of installers didn’t understand the difference and non ball bearing hinges would end up on doors with closers. Not a good thing.
Hinges are as varied as the doors that hang from them. While most building products are measured width x height, door hinges are measured height by width; and the width is the total opening measurement of both leaves of the hinge.
Specifying & Sizing Hinges
To determine the height of the hinge this graph is helpful:
The general rule for the quantity of hinges for a door leaf is one hinge for every 30” of door height. A typical 7’0” door would require 3 hinges; an 8’0” tall door – 4 hinges.
Keeping this in mind on the lead side of a-fabco’s business we manufacture vault doors that can weigh 22,000 lbs. This handy dandy hinge from Brookfield Industries is so heavy I could barely move it in order to take pictures.
There are also many hinges to solve special door opening dilemmas. Lori Greene just wrote a great blog post explaining 4 different types of commercial hinges and the application in which you would use them.
Being on the commercial side, I don’t often get into the sexy hinges but had to throw in a few for good measure because I know how JB loves sexy hardware.
Like these strap hinges that can be used on gates or shed:
Making sure a door is hanging from the right hinge will prevent all sorts of future issues.
I also want to say thank you to JB for asking me (about 100 years ago) to write a post for this blog. I am sorry it took so long.

Excellent primer, Ginny! My knowledge of hinges now hinges on this blog!
We’ve opened the door to some great puns with this one!
I’m sure we have, but it will still never approach the critical mass of squirrel puns!
(My reputations hangs in the balance here! :-)
JB, You went to the right place for door hardware expertise. Very informative post, I did like the sexy hinges best! Great post, Ginny
Ginny, a really great post. Must say, I fear the 5″ hinge when I’m working on a door. Only encountered a couple of times, but sheesh… indicates a sore back is coming.
The vault door hinge is pretty cool. As we work in the residential realm, most of the unique hinges we see are in historical restorations. Several times while working on rehabs, I’ve had to root through boxes of salvaged hinges at an antique store to find the right one we need. The details on some of those deco hinges are one of a kind.
Amanda thanks for your support!
Paul – sexy hardware talk is a post I would love to write someday but hard to make it G rated!! You are right 5″ hinges typically mean some heavy doors! Take picture of unique hardware you find! Actually a small wall full of antique hinges would be cool.
Nice article, Ginny! As you’ve shown, there’s actually quite a bit to a hinge. I am with Paul and jb, I suppose, on the sexy strap hinges and historical stuff. The lead door hinge was pretty amazing, though!
Thanks John! When I went to move the Brookfield hinge one of the guys watched. He knew what I didn’t – it wasn’t going to budge and it didn’t!
Amanda, as always, thanks for your support!
Paul I would love to write an entire post on hardware related words but don’t think it can be G rated! I think a small wall decorated with unique hinges would be a cool design feature!!
The fact that I understand most of the lingo you used here makes me proud! *sniffle* Great blog. Now if we could just get the installers to review this…
Lacey I am so proud! I hope you are sharing that with John and Mike!!
OOohhhh, AAAhhhhh. Love those hinges. Strap, decorative, whip, leather….oh, um, where were you going with those adjectives exactly? Anyway, I’m glad you wrote this post. And John should do another about squirrels and trap hinges if he wants to keep his reputation!
Hey Ginny – Great post on hinge basics. Thanks for mentioning my blog post!
Alexandra – Those are the perfect adjectives for the hardware industry! We also talk about sex nuts.
Lori – Your blog rocks for our industry. Thank you!
Great post Ginny, very informative. Enjoying all the comments also :)
