How to Measure Garage Door Springs – An Easy Measuring Guide


An automatic garage door will provide you with the security and comfort that your vehicle deserves. The automatic remote opening system provides peace of mind for those who enter or leave your home with your car. Spring is the main component responsible for the system’s smooth operation. To ensure that you can continue enjoying your system, keeping spare parts on hand is a good idea. It is essential to measure your measurements accurately to get this. There are many options on the market, and this can cause problems. We will provide all information necessary to measure garage door springs.

How to measure garage door springs

The garage door opener; the counterbalance is provided by the garage door spring to allow for the lifting of the door. There are also extension springs and another garage door spring. The door will open and close by working together. We will now show you how to measure springs. First, measure the inner diameter. Next, measure the width of your opening using a tape measure. They usually measure 2 inches. The length of the spring.

It is important to only measure the structure of the resort. It is essential to measure the spring without considering the cones or aluminum caps. Tension springs typically measure 23 inches. The most crucial step is to gauge the wire. This will ensure that you buy the same size wire with the same strength and capacity. This will ensure that the garage door is in good working order. Let me explain 3 easy methods to measure garage door springs.

The caliper is a valuable tool to measure and manipulate items. It is a ruler with a sharp corner and can be inserted into grooves for what’s called “spring action” on paper and cardboard. Count 20 lines and then insert them. This will give us the measurement of our caliper. This is the exact way to get an exact measurement.

Method 2

A digital caliper is required. You should also know how an analog scale works with a Vernier or a caliper. This method can use if you have the support of a professional or an experienced person.

Method 3

Although it’s more accurate than the other methods, the Flexometer is still prevalent. This is how you place the Flexometer in inches. At the spring’s beginning, count 20 threads. Mark the Flexometer with paint, and then divide the result by 20. After counting 20 wires, 14 inches is the measurement. Divide 14/20 = 0.75, and 0.7 will be our wire gauge. These measurements will allow you to purchase the replacement spring or service. You can also have it changed or kept as a spare.

Extension springs to sectional Doors

Sectional garage doors can be hinged and folded into the tracks for opening and closing. The balance with extension springs that allow heavy lifting loads. The coil’s size and length must adjust to stretch broader or shorter. There are four coils in between each piece, ensuring even distribution across the entire band. The spring’s length is usually equal to the height of the door. It exerts the force of the spring’s energy; pulls when it stretches to its average length. How you mount, the spring’s ends will depend on the type of end.

The initial tension is the amount of pull required to separate the coils. This determines the pitch at which springs will wound. It is usually 15 percent. A 100-pound tension spring will require 15 pounds to separate its coils. When a door is opened, the springs will support the door weight of 15 pounds without stretching.

Extension springs one-piece doors

These single-piece extension springs for doors are notable. For your door to function normally, it must be the correct springs. One-piece garage door springs are tighter than sectional extension springs and don’t work as well. One-piece springs come in two forms: the first is the standard, which is used by many door manufacturers. The rollers at the top of the door move along a track made of metal that extends horizontally towards the garage’s back. Standard one-piece, single-panel garage doors extension springs are available if your system is compatible. Holmes single-panel or one-piece springs are other options. These springs can use with different hardware so that the top of your door doesn’t slide along the horizontal tracks. The pivot assembly supports the door’s weight. Drums, winding cones, and stationary cones complement the operation.

Describing the spring wind

The spring wing, also called wound, is one of the most misunderstood facts regarding springs. Spring wind is the direction in which the wire is wound to create a spring. It is helpful to determine the direction in which the spring will uncoil when the door moves up or down. The spring cones may have threads that match spring’s wind or universally mount.

A typical garage door setup has a left-hand-winding spring mounted on the right side and a righthand-winding spring on the left. Although there are exceptions, this rule is generally recommended for basic engineering. The spring’s winding cones can be color-coded to help you identify the spring’s wind. Right-wound springs have red cones, while those on left-wound are black. These colors may fade or become non-existent, so it is essential that you can determine the wind speed of spring without using color coding.

Finding a torsion length

The length of a garage door spring is perhaps the most important thing to measure. The spring’s length directly influences its winding capacity. A spring that can lift a heavy garage door will require. Measure the length from the spring end coil to the spring end coil. Do not include the cones that use to measure the torsion spring. The spring length measurement must take to within a quarter inch.

Finding inside diameter

Next, measure the inside diameter of torsion springs. Measure from the inside of the spring coil to the outside using a tape measure (or caliber). This measurement will give you the spring’s diameter. For accuracy, measurements must take inches. You can check the number etched into hardware to verify that the spring you measure is fitted with spring fittings (cones, drums). Spring fittings for 1-3/4-inch ID torsion springs will show a 175 as an example. The torsion spring ID generally refers to standard width. The chart below lists the standard inner diameters of torsion springs.

Finding the wired size

Measurement of a garage door’s torsion spring ends with determining its wire size. You can measure the wire size using a spring wire gauge, a pocket gauge, or some simple math formula. These three methods can use to determine the size of a spring’s wire. They are both precise and straightforward. Use a spring wire gauge to count the coils. To determine the size of the wire, you can look at the numbers on the gauge after reaching the 20th coil. If you have a pocket gauge, you can match the coil key to the wire size to find the correct wire size.

You can use this trusted math formula to determine the size of the spring wire gauge if you don’t own a spring wire gauge. Start by counting 10 to 20 coils of the torsion spring. Use your tape measure to measure the coils. Divide the measurement by counting coils (10 or 20). You will get the answer to the equation if you know the spring wire size that you measured. Take the closest 1/16 inch measurement.


All the research is done to determine how to measure garage doors springs. This equipment can use to get the correct information. This will enable you to measure garage door springs to find the right replacement spring for your needs. Garage doors’ springs are an integral part of daily life. Garage doors must open at least twice a day when you drive to work, to the grocery store, or to places of recreation.

The garage door’s mechanical parts are like equipment in a typical home. Garage torsion springs may wear out throughout a typical home tenancy. To measure the length of a garage door spring’s broken half, you will need to bring them together on a flat surface. Play the broken ends together and draw a tape measure across the entire length.
