How To Measure Scope Ring Height?

When measuring scope ring height, it is important to use a caliper. This will ensure that you get an accurate measurement. Place the jaws of the caliper on the top of the scope ring and measure from the bottom of the jaw to the top of the scope ring.

This is the height of your scope ring.

  • There are a few different ways that you can measure scope ring height, but the most common and accurate way is with a set of calipers
  • First, you will need to remove the scope from the gun
  • Once the scope is off, take one of the calipers and place it on top of the scope base
  • The second caliper goes on the bottom of the base (or rings)
  • Make sure that both calipers are lined up evenly, then take a measurement
  • Repeat this process for the other side of the scope base (or rings) to get an accurate measurement

How is the Height of Scope Rings Measured?

When it comes to scope rings, the height is measured from the centerline of the bore to the top of the ring. This is important to know because it will dictate how high or low your scope will sit on your gun. For example, if you have a high-mounted scope, you’ll need high rings so that the optics are level with your eye.

Conversely, if you have a low-mounted optic, you’ll need low rings. The measurement is usually given in inches or millimeters and can be found in most product descriptions. Now that you know how scope rings are measured, you can choose the right ones for your needs.

If you’re still unsure, consult with a firearms expert or retailer before making your purchase.

What are the Different Heights of Scope Rings?

There are many different heights of scope rings. The most common are low, medium, and high. Low rings are typically used on handguns and rifles with short barrels.

Medium rings are used on most rifles, while high rings are reserved for long-range rifles or those fitted with large objective lenses. Extra-high rings may also be necessary for special applications such as mounting a red dot sight in front of a magnified optic. The height of the ring is measured from the top of the base to the centerline of the scope tube.

This measurement is known as the ring height. Most manufacturers offer a variety of heights for each ring size so that you can select the best one for your application. When choosing scope rings, it’s important to pick a pair that have the same height.

Mixing and matching heights can result in an uneven sighting plane, which will make it difficult to get an accurate shot. If you’re unsure which height to choose, err on the side of caution and go with a taller set of rings. You can always shim them down if needed, but you can’t add material back if they’re too low.

How High Should a 50Mm Scope Ring Be?

There is no definitive answer to this question as it depends on a number of factors, including the make and model of the rifle, the type of scope, and the shooting discipline. However, there are a few general guidelines that can be followed when choosing the height of scope rings for a 50mm scope. For most rifles, medium height rings (30-34mm) will work well.

This will allow for a clear sight picture and plenty of clearance between the top of the scope and the barrel. For bolt action rifles or those with high recoil, high height rings (35-42mm) may be necessary to prevent damage to the scope during firing. If you are using a fixed power scope or one with a large objective lens (44mm or larger), then extra high rings (43-50mm) will be needed to provide adequate clearance.

These taller rings will also help to reduce parallax error at long range targets. When mounting a 50mm scope on an AR-15 platform rifle, special considerations must be made due to the forward placement of the handguard rail. In this case, ultra high rings (50-60mm) are recommended in order to maintain proper eye relief and prevent interference with charging handles or other accessories mounted on the rail.

How a Scope is Measured?

A scope is measured in two ways: by its objective lens and by its magnification. The objective lens is the front lens on a scope, and it’s what you look through to see your target. The size of the objective lens is important because it determines how much light can enter the scope.

A larger objective lens will let in more light, which means you’ll be able to see your target better in low-light conditions. The magnification is the number that’s written on the side of the scope, and it indicates how many times bigger your target will appear through the scope than if you were looking at it with your naked eye. For example, a 4x scope will make your target appear four times bigger than if you were just looking at it with your eyes.

How to Measure Scope Ring Height With Pennies

When you’re ready to mount your scope, one of the first things you need to do is measure the ring height. This will ensure that your scope is mounted at the correct height, allowing you to get the best possible accuracy. There are a few different ways to measure scope ring height, but one of the easiest is with pennies.

All you need is a stack of pennies that’s equal to the desired height of your rings. For example, if you want 1-inch high rings, then use 20 pennies. Once you have your stack of pennies, simply place them under the scope until they’re touching the barrel.

Then, take a look through the scope and adjust the eyepiece until you can see clearly. Once everything is in focus, make a mark on both the penny stack and the barrel so you know where to align the rings when mounting them. Now all that’s left is to mount your rings at the correct height!

Using this method, there’s no need for special tools or expensive equipment. All it takes is a little bit of time and patience to get everything just right.


To measure the height of your scope rings, you will need a ruler or a tape measure. Place the ruler on the top of the scope ring and measure from the bottom of the ring to the top. If using a tape measure, wrap it around the circumference of the scope ring.

The height measurement will be slightly different depending on which method you use, but it will give you a good idea of how high your scope rings are.
