How to Choose the Right Hinge for Door

Door hardware is an important part of the door, in the design and calculation of door hardware selection, hinge as a load-bearing component, has an important position. The bearing capacity of hinge affects the safety performance and service life of the whole door.

 

These door and frame factors influence hinge selection:

Door and frame material

Frequency of use Environment

Door weight

Door width

Door control hardware

Labeling requirements

Projecting trim

Location of opening

 

Select the proper weight and bearing structure

Because of the large variety of door size and weights, hinges are placed into three groups:

Heavy weight – Ball bearing

DDSS001-ANSI 

 

Standard weight – Ball bearing

DDSS001-45453 

 

Standard weight – Plain bearing

Stainless-Steel-Round-Corner-Door-Hinge-DDSS006 

 

There are two factors that determine the weight and structure of the hinge, mainly weight of door and frequency of use.

The weight of the door is based strictly on how much the material of the door weighs. It also is advisable to include the approximate weight of additional hardware that will be installed on the door.

Use below table for estimating the door weight because other factors, such as installed hardware, also affect the total weight of the door.

The next factor is the frequency of use. How often is the door opened and closed in a given time frame? This usually is figured on a daily basis.

Below table lists the expected frequency of operation of various types of openings.

These frequency chart recommendations apply to all average weight doors, Heavy ball bearing hinges should be used for larger doors (i.e. doors having a thickness of 2” or more and over a width of 3’4”.)

Another critical note which often is neglected relates to doors on which a closing devise is used. These doors should be equipped with ball bearing hinges, regardless of frequency of use.

 

Determine the size of hinge:

In order to determine the proper size of the hinge, several bits of information will be necessary:

Door Height    Door Width     Door thickness     Door Weight       Trim Dimension Required

 

Below table lists the hinge sizes recommended for various size doors:

Heavy weight hinges should be specified for heavy doors and for doors which are expected to receive high frequency use.

 

Determine the width of hinge:

Using hinges that are wider than needed results in poor appearance because the hinges will be unnecessarily prominent. For the sake of appearances, never select hinges wider than necessary to clear the trim.

Manufacturers publish a formula for correctly determining the width of full mortise hinges. Full mortise hinges are available in several standard widths. Choose the next closest width to satisfy the opening conditions.

Note: Hinge back-set for 1-3/8”, 1-3/4” and 2-1/4” thick doors is 1/4”. For doors more than 2-1/4” thick, the hinge back-set is 3/8”. Confirm hinge back-set dimension with door manufacturer.

This formula would apply only to full mortise hinges.

Determine the quantity of hinge

In our industry there is a rule used to determine the number of hinges needed per door: one hinge for every 30” of door height or fraction thereof.

The intermediate hinge(s) help to carry the weight of the door and keep the door properly aligned in the frame, increasing the life span of the entire opening.
