How to Measure Garage Door Springs | Measure Garage Doors Springs

Having an automatic garage door is very important for the comfort and security to protect your vehicle. Its automatic and remote opening system generates peace of mind when entering or leaving your home with your vehicle. The main part responsible for the system’s correct operation is the springs. It is recommended to have spare parts in case of failure to achieve immediate replacement and continue to enjoy. To obtain this, it is imperative to know your exact measurements. In the market, there is an uncountable variety, and it can be an inconvenience. For such reason, we will supply all the necessary information to decipher; how to measure garage door springs.

How to Measure Garage Door Springs

The automatic garage door mechanism; counterbalance with the help of the garage door torsion spring, allowing the lifting of the garage door. We also find another type of garage door spring, as are the extension springs. Working together allows the opening and closing of the door. For this reason, we will show the steps to measure the springs:

  • Measurement of the internal diameter; for this, we need a tape measure, with which, in a straight line, we will measure the width of the opening. Normally they measure 2 inches.
  • Length of the spring; it is necessary to take only the structure of the resort. You should not measure it without taking into account the aluminum caps or cones. Tension springs normally measure 23 inches.
  • Wire gauge is one of the most important steps since it will guarantee that we will buy the same wire size with the same capacity and strength. In this way, we will avoid problems when making its normal operations the garage door.

There are three methods to make this measurement, which are:

  • A caliper is an important tool for measuring and manipulating items. It consists of a ruler with a small, sharp point in the corner that can be inserted into grooves to achieve what’s known as “spring action” on materials such as paper or cardboard. In this way, count 20 lines while inserting them. At this point, we will obtain the measurement of the caliper. This is the exact method that will generate an accurate measurement.
  • You must have a digital caliper or know how an analog caliper works with a caliper or Vernier. Use this method if an experienced person or a professional is available to assist you in obtaining accurate measurement data.
  • Using a Flexometer; is a very used method, although it is not as accurate as the others. In this way, place the Flexometer in inches; on the beginning of the spring and count 20 threads. At this point, we measure by marking with paint and divide the result by 20. For example, the measurement after counting 20 wires is 14 inches. We will divide 14/20 = 0.7; therefore, 0.7 is the gauge of our wire.

With the collection of these measurements, you can buy the replacement spring or service; you need to change it or have it as a spare.

Extension springs for sectional and one-piece doors.

how to measure garage door springs

Sectional garage doors are hinged and fold into the tracks when opening and closing. Thus, they are counterbalanced with extension springs allowing the lifting of heavy lifting loads, with different operating characteristics:

  • The size and length of the coil can be adjusted to create a wider or narrower stretch. As a result, there are four coils between each piece that will ensure even distribution throughout the entire band.
  • The distance the spring is stretched, usually half the height of the door. Thus, it exerts the force and energy of the spring; pulls when stretched to its normal length.
  • The type of ends; determines how you mount the ends of the spring. So, the initial tension is the percentage of pull you need to separate the coils. This will determine the pitch at which the springs are wound; typically, it is 15 percent. For example, a 100-pound tension spring requires 15 pounds to separate the coils; when a door is open, the two springs will support 15 pounds of door weight without any stretch.

What about one piece?

One-piece single-door panel extension springs are noteworthy. They must be the correct springs for your door to operate normally. One-piece garage door springs; coil tighter and do not function the same as sectional door extension springs. There are two types of one-piece springs:

  • The first is the standard spring, used by a variety of door manufacturers. The top of the door has rollers that move along a metal track, which extends horizontally toward the back of your garage. If your system matches, you have standard one-piece, single-panel garage door extension springs.
  • The other style of spring; is the Holmes one-piece or single panel door spring. These springs are used with different hardware, so the top of the door does not slide along the horizontal tracks. The pivot assembly supports the door’s weight; drums, winding cones, and stationary cones; complement the proper operation.

Why adjust and service garage door springs.

The springs of an electric garage door compensate for its weight, allowing it to open and close with ease. If there is a problem with the spring tension, the gate will open or close incorrectly or at the wrong speed. 

For this reason, adjusting the springs will solve and prevent this type of problem and a hasty repair. Electric gates come in different styles; they use two different types of springs, depending on the style of gate you have to maintain.

Common spring failures

  • Coiled springs on the left-wound springs.
  • Coiled springs on the right-wound springs.
  • Some coiled spring on the left.
  • Coiled torsion spring.
  • Broken spring due to lack of maintenance or pressure.

Frequently Asked Questions

Does garage door torsion spring length matter?

Replacing a wound torsion spring that is too large or too small with the correct size can rebalance the door and restore its safety. The door will lift more easily and keep securely in position.

For how many rotations does a 7-foot garage door spring make?

A 7ft tall door requires 7.5 full rotations or 30 to 31 quarter turns, whereas an 8ft tall door requires 8.1 full turns or 33 to 34 quarter turns.

Would you please explain why my patio door only has one torsion spring?

Because many builders install one spring on a garage door when they install the door, that implies it doesn’t require two or more springs.

How many turns on a garage door tension spring?

With the spring, four one-quarter turns are one full revolution. In addition, the spring must be tensioned one full revolution for each foot of door height (e.g., 7-1/2 ft. door = seven +2 rotations). (30 quarter turns).

Can I put a bigger spring on my garage door?

If your garage door springs have lasted fewer than five years, or if you want to stay in your current location for a long time, you may want to consider the extra-long life torsion springs. In most situations, employing bigger springs can double your spring life while just doubling the cost of the springs.

Can garage door springs be too strong?

An incorrect size spring can present major problems for your garage door(s). A well-adjusted spring or spring will result in a well-balanced and safe garage door. A too-small spring or too large can damage the motor, wear out the cables and create a safety issue, among other things.

Does my garage door need a spring?

These springs are critical for your garage, your garage’s opening and closing, especially if you have two.

Does a garage door need two springs?

Extension spring doors should always have two springs. The two collaborate to give a counterbalance to the door. Replace both springs if one of your garage door springs breaks or is in bad condition.

What do the colours mean on garage door torsion springs?

A torsion spring’s colour code specifies a “right wind” or “left wind” spring, with black signifying right wind and red suggesting left-wound spring.

Should garage door springs be the same size?

If you don’t have a balance in the door, it will open too much or too little.

How many twists do I need for a garage door spring?

The number of rotations necessary on your garage door springs is the height of your garage door. If your door is 7 feet square, we highly recommend that you comment with 31 quarter-turns on each spring. If you have an 8-foot door, start with 34 quarter turns.

Why are garage door springs so dangerous?

Where the danger lies is in what would happen if the springs should break unexpectedly. With the spring under continuous tension, a sudden failure could cause the spring to break abruptly.

Bottom Line

We have all the necessary research to solve; how to measure garage door springs. The correct use of this equipment will guide us to obtain the correct and specific information. It will allow you to obtain the necessary measurements to acquire the replacement spring that meets your needs.

The springs of garage doors are integral components of everyday life. When driving to and from work, the grocery, or places of recreation, you need to open the garage door two to four times each day. As a result, the mechanical components that operate a garage door work as pieces of equipment in the average home. As a result, garage torsion springs can wear down throughout a typical home tenancy.

When a garage door torsion spring snaps in half, you must bring both halves together on a level surface to acquire an accurate length measurement. Therefore, play the two broken ends together, and then draw a tape measure over the whole length.
