DASMA stands for the Door & Access Systems Manufacturers Association. This is the organization responsible for developing the guidelines and specifications for garage door spring color codes. The color codes are supplemental aids to help identify the correct springs. Because springs all look so similar, the codes help consumers find the right springs and they help retailers keep products organized ensuring the right spring gets to the customer.

If you have two springs on a residential or commercial door, it is critical that you measure both springs. Approximately 30% of manufacturers and service companies mix wire sizes. Following the steps below will help in getting the correct dimensions.
Likewise, if you have a linear system on a commercial door, make sure that you measure each of your springs. If you have a duplex or triplex system, make sure that you know the inside diameter and wire size for the inner spring(s) and all five characteristics of the outer spring.
Torsion springs grow one coil in length, with each turn of tension applied to them. The gain in the spring length is replaced with small gaps between the coils when you open your garage door because the setscrews do not move on the shaft, so you cannot open your door to measure the spring length. Measuring a wound spring requires determining the number of turns on the spring.
Also, if you have a residential garage door with standard 4" cable drums, simply deduct from the total spring length the number of coils added when the spring was originally wound. On seven-foot high doors, this would be eight coils, and on eight-foot high doors, it would be nine coils.
For example, on a seven-foot high garage door, a 34" spring comprised of .250 wire would grow eight coils when it is wound and stretched. The spring will grow 7.5 coils, or 7.5 X .250 for the coil size, or 1 7/8". Springs are usually stretched an extra 1/8", so the total addition to the spring length is eight coils or two inches. The 34" spring will measure out at thirty-six inches. Deducting eight coils from the total length will provide an accurate length of thirty-four inches.
There is another way to determine the number of turns on the springs on larger standard lift industrial doors or residential doors with non-standard drums. Measure the circumference of the cable drum, and measure the height of the garage door in inches. Divide the height of the garage door by the cable drum circumference, then add one. This is the number of turns that are on your spring. For example, a 14' high door is 168" high. Many of these have drums with 17" circumferences. Dividing 168" by 17" would give you 9.88. Add one to this, and you get 10.88 turns, and with a little stretch, a total of 12 coils. Deducting 12 coils from the total length will give you an accurate length of the spring when it is unwound.
If you measure springs on a larger commercial or industrial door and there is not a paint stripe, and if you have a vertical-lift or high-lift garage door, it will probably be easier for you to unwind the springs than to calculate the length of the spring.
The only accurate way to measure the wire size is to measure 10 and 20 coils. Since the coils rub together when the garage door operates, the sides of the coils are less impacted by corrosion. In addition, when springs are painted, the paint does not get between the coils. The 10 and 20 coil measurements are highly accurate.
The spring wire remains the same size after it is wound, so the measurements will not be affected. We measure both springs because about a third of the garage doors installed have unmatched springs on them. Manufacturers do this to minimize cost; service companies do it to minimize inventory. Replacing with matched torsion springs will allow you to maximize cycle life.
If you look at the chart above, you'll notice that there are several items in bold. These measurements are nearly equivalent to the naked eye if you measure them improperly. It is absolutely necessary that you do the 20 coil measurement for accuracy on this particular measurement. If you don't measure properly, you can get a spring that is not strong enough for your garage door.
Commercial and industrial doors, depending partly on their weight, use torsion springs with inside diameters all the way up to 8-1/2". The markings on these cones are similar: "334" or "375" refers to 3-3/4", "600" corresponds to 6", etc.
On most residential garage doors, the spring to the left of the center support bracket is right-wind, and the spring to the right is a left-wind spring. In other words, the right wind spring is typically on the left side above the garage door, and the left wind spring is above the right side of the door as you view the door from inside the garage.
Since measuring the springs can be so difficult, many customers prefer to provide the garage door width, height, and model number. The model number is often embedded in the serial number or PID number located at one end of the garage door.

Home Torsion SpringGarage Door Torsion Spring Size CalculatorJune 21, 2023April 2, 2023 by Furqan AbrilGarage doors come in various sizes and styles, and it is essential to select the right torsion spring size to ensure that the garage door functions optimally.
Second, using the wrong size can cause damage to the garage door or opener. If the spring is too small, it will put extra stress on the garage door opener, causing it to wear out faster. If the spring is too large, it can cause the garage door to bend or warp, leading to expensive repairs.
The first step is to measure the height and weight of the garage door. Measure the height from the floor to the top of the garage door, and measure the weight by placing a bathroom scale under the center of the door and reading the weight.
Next, choose the type of track used for the garage door. There are three types of tracks: standard, low headroom, and high lift. The track type will affect the amount of clearance available for the spring, which will impact the recommended size.Step 3: Select the Desired Cycle Life of the SpringFinally, select the desired cycle life of the spring. The cycle of life refers to the number of times the spring can open and close before it needs to be replaced. A higher cycle life means a longer-lasting spring but may come at a higher cost.

The calculator will generate a recommended wire size and diameter based on the information you provided.
The weight of the garage door is one of the most important factors to consider when determining the size of the torsion springs required. The heavier the garage door, the stronger the torsion springs need to be.Height of the Garage DoorThe height of the garage door also affects the size of the torsion springs required. The taller the garage door, the longer the torsion springs need to be.
The track radius refers to the curvature of the horizontal track that the garage door rollers ride on. The track radius affects the size of the torsion springs required.ConclusionA garage door torsion spring-size calculator is a valuable tool that helps ensure the safety and longevity of your garage door system.By taking into account the height and weight of the door, track type, and desired cycle life, the calculator generates a recommended wire size and diameter for the torsion spring.
Use the following chart to determine the strength of each spring as measured in Inch Pounds Per Turn (IPPT). Your garage door requires a specific TOTAL IPPT, which can be achieved by using one or multiple springs.
The service life indicated by the calculator is based on estimated spring material stress and typical spring steel resistance to failure through fatigue.The actual service life may vary depending on the specific spring model, coating, corrosion, rubbing, and so on.

The calculation of spring pitch is different depending on the type of ends. Below are the formulas for the types of ends which are provided in our spring pitch calculator. These types of ends are closed and squared, closed and ground, double closed, and open ends.
Note: if adding a garage door opener onto an existing door: if you have 12" (305 mm) headroom with torsion spring operation, and you would like to install an electric operator, special top brackets (quick turniing brackets) are available.
Some familiar examples of uses are the strong, helical torsion springs that operate clothespins and traditional spring-loaded-bar type mousetraps. Other uses are in the large, coiled torsion springs used to counterbalance the weight of garage doors, and a similar system is used to assist in opening the trunk (boot) cover on some sedans. Small, coiled torsion springs are often used to operate pop-up doors found on small consumer goods like digital cameras and compact disc players. Other more specific uses:
