Brace height is among the most crucial metrics of recurve archery. That’s why you frequently see archers inspect whether their brace height has actually altered. If your brace height modifications, so will the flight of the arrows. For that reason, in this post we go over whatever there is to learn about brace height.
Initially, I will discuss what brace height precisely is and how you determine it. Next, I will go over how to set on your bow and what brace height is suggested. At the end of this post, we will go over the significance of brace height in more information and what you must do to keep your brace height in check.
What is brace height?
Brace height is the range in between the string and the inmost part of the grip, determined in a straight line while the bow is not drawn. This measurement is a standardized method to show the quantity of pretension there is on your bow.
You can determine the brace height with a ruler, however the very best tool is to utilize a bow square. Particularly if you are shooting a recurve bow, you will inspect your brace height a lot. For that reason, I do advise purchasing a top quality bow square like this one from Easton.
If you have a long brace height, the bow is under a great deal of pre-tension. If you have a brief brace height, the bow is under little pre-tension. Likewise, the shape of the riser can substantially affect the brace height, for that reason you can’t make precise contrasts of brace height in between various substance bows.
We desire our brace height to be as constant as possible since it affects the speed of the arrow and hence the quantity of arrow drop.
Brace height on recurve bows
Let’s very first go over how brace height deal with recurve and standard bows. In the next area, I will describe how brace height deal with substance bows
Changing the brace height on recurve bow
To change the brace height on a recurve or standard bow you require to include or eliminate twists from the string. Including twists will increase the brace height and getting rid of twists will reduce the brace height
To include or eliminate twists, you initially require to unstring the bow. You require a gadget called a bowstring, which you connect to the limbs. I advise this bow stringer since it needs the least strength to utilize and is much safer for the limbs.
You can see how to utilize a bow stringer in the video listed below. This video demonstrates how to string a bow. To unstring the bow, you do whatever in reverse.
Once the bow is no longer under stress, you merely eliminate among the 2 loops and include or eliminate some twists.
Making big brace height modifications
There is just a lot you can do with including and getting rid of twists. Including or getting rid of more than 20 twists isn’t suggested since that can reduce the life-span of the string. If the brace height requirements to be changed an inch (3 cm) or more, it’s much better to change the whole string.
If that holds true, you most likely have a string that isn’t an excellent suitable for your bow. You may wish to check out the post listed below for suggestions on how to pick the best string length:

Why you must routinely inspect your brace height
If you contend an archery club, you most likely see that a great deal of archers are examining their brace height prior to shooting. Recurve strings extend a lot, particularly if they are brand-new. For that reason, it’s suggested to routinely determine your brace height.
If your string is just a couple of months old, you must inspect it a minimum of every 2 weeks. As soon as your string grows older, you can inspect it less frequently. Old strings hardly extend. Still, I would inspect your brace height every when in a while.
For that reason, make certain to compose your brace height down. If you observe that your brace height has actually reduced, you must include a couple of twists to get it back to the suggested brace height.
If you observe that your brace height keeps altering even on an old string, you may wish to provide the post listed below a read:

Suggested brace height chart
A lot of archery producers note their suggested draw weight either on their site or the owner’s handbook. It’s constantly best to utilize this if you can discover it. If that isn’t offered, you can utilize the table listed below to discover the suggested brace height.
| AMO bow length | Minimum brace height | Optimum brace height |
| 58 inches | 7 1/4 inch (18.5 cm) | 7 3/4 inch (19.5 cm) |
| 60 inches | 7 1/2 inch (19 cm) | 8 1/4 inch (21 cm) |
| 62 inches | 7 3/4 inch (19.5 cm) | 8 1/2 inch (21.5 cm) |
| 64 inches | 8 inch (20.5 cm) | 8 3/4 inch (22 cm) |
| 66 inches | 8 1/4 inch (21 cm) | 9 inch (23 cm) |
| 68 inches | 8 1/2 inch (21.5 cm) | 9 1/4 inch (23.5 cm) |
| 70 inches | 8 3/4 inch (22 cm) | 9 1/2 inch (24 cm) |

To utilize this chart, you require to understand your AMO bow length. On a lot of bows, you can discover this details printed on the lower limb, near the riser, or the limb fitting of the bow. You can likewise determine your AMO bow length by following the directions in the video listed below.
How your brace height may trigger problems
It’s a finest practice to keep your bow within the suggested brace height. This will guarantee optimum shooting efficiency and will strain the bow the least. A brace height that is too long will trigger the limbs to flex more than they are created for. This is particularly the case if you shoot a heavy draw weight.
Having a too brief brace height can likewise restrict your bow’s life-span. The limbs may spring forward excessive which can trigger extra stress on the limbs. In addition, a bow with a too-long brace height can trigger hand slap which can be exceptionally uncomfortable.
For the most part, it’s much better to have a brace height that is a bit longer than a bit too brief. A bow with a long brace height is more flexible for errors of the archer. I go over how this operates in more information, later on in the post.
Brace height on substance bows
Brace height is fairly easy on recurve bows. You merely twist the string to increase or reduce the brace height. Unfortunately, it isn’t that easy on substance bows. Twisting the string will do little to alter the brace height.
Why you can’t change the brace height on a lot of compound bows
You can’t alter the brace height on a lot of compound bows since a lot of substance bows have parallel limbs. For that reason twisting the string will not increase or reduce the brace height.
Substance innovation keeps establishing. One current improvement is the orientation of the limbs. Older substance bows have limbs that were angled at about 45 degrees, comparable to recurve bows. A lot of more recent substance bows function parallel limbs, which suggests that the limbs are horizontal.
The advantage of parallel limbs is that they vibrate less than angled limbs. Considering that both limbs relocate an opposite instructions the vibration will counteract. I describe how this operates in more information here.
Parallel limbs likewise have a drawback, you can’t alter the brace height. On a recurve bow we increase the brace height by twisting the string which will pretense the limbs more. This will trigger the limbs to flex backwards which triggers the brace height to increase.
If we alter the stress on parallel limbs, the string and cable televisions will remain in the exact same position. When the limbs are parallel, they aren’t drawn back, however inwards. For that reason, it’s not possible to alter the brace height on these substance bows.
How brace height varies per substance bow
In between various substance bow designs, the brace height can differ extremely. This is triggered by the shape of the riser. Some substance bows have a straight riser, which triggers the brace height to be rather long. Other substance bows have risers that are angled inwards, which will make a much shorter brace height.
In basic, bigger brace heights are more flexible. For that reason, these are primarily discovered on target substance bows. A lot of searching substance bows function an angled riser since this increases the arrow speed. I go over how this operates in more information later on in this post.

Changing the brace height on a substance bow
To change the brace height on a substance bow, follow these actions:
- Put the bow in a bow press
- Tighten up the bow press and eliminate the stress from the limbs
- Include twists to both cable televisions to increase the brace height and eliminate twists to reduce it
Make certain to include or eliminate the exact same variety of twists to both cable televisions, if you have 2 cable televisions. Otherwise, the cameras may shoot out of positioning which can trigger your arrow’s flight pattern to alter.
Much like a recurve bow, increasing the brace height will likewise increase the draw weight of the bow. For that reason, beware and do not increase the brace height excessive. Otherwise, the limbs may be under excessive stretch which can reduce their life-span.
If your wish to alter the brace height by more than 1/4 inch, it’s most likely much better to purchase a brand-new substance bow. Considering that substance bows are angled more than recurve bows you can’t increase the brace height all that much.
Why brace height is necessary
Brace height is a crucial metric since it considerably affects the forgivingness and speed of the arrow. For that reason, you desire a constant brace height that matches your requirements in archery.
In this area, I will describe in more information just what the advantages are of these various brace heights.
The advantages of a brief brace height
Bows with a brief brace height have a greater arrow speed. This is advantageous for nearly all archers. It reduces arrow drop, permits you to shoot much heavier arrows, and makes the arrow more wind resistant. I go over the advantages of increasing the arrow speed in more information in this post.
It may be counter-intuitive that reducing the brace height boosts arrow speed since you do this by reducing the quantity of pre-tension. However if you think about the length of the power stroke it makes a great deal of sense.
The power stroke is the quantity of draw length the string needs to speed up the arrow. A brief power stroke will less effectively move the draw weight to the arrow than a long power stroke. We can determine the power stroke with the following formula:
” Power stroke length = draw length– brace height”
For That Reason, if we keep the draw weight the exact same however reduce the brace height, we increase the power stroke. On recurve bows, the distinction is small, however on substance bows, this can make a substantial distinction. That’s why a lot of searching bows have a brief brace height.
You can quickly see the distinction in between the brace height of the 2 bows by taking a look at the risers. The target bow has a straight riser to take full advantage of the brace height. The riser of the searching bow flexes more inwards to reduce the brace height.
The advantages of a long brace height
Having a long brace height likewise has some crucial advantages. That’s why target substance bows have a rather long brace height. The longer brace height makes the bow more flexible since the arrow leaves the string previously.
A longer power stroke provides the archer more time to flinch or jerk. For that reason, to make a bow as flexible as possible, you desire it to leave the string as early as possible. Among the methods to accomplish this is by increasing the brace height.
In the end, it’s everything about stabilizing these 2 evils. A longer brace height may be more flexible however likewise makes it harder to shoot the bow at longer varieties and in windy conditions.
Another crucial advantage of a longer brace height is that you have more clearance with your sleeve. Particularly if you regularly shoot throughout winter season, the string may get captured in your sleeve while shooting your bow.
Another typical problem with a brief brace height is string slap. The string will shoot forward excessive which triggers it to strike your hand. This is exceptionally uncomfortable and is more than likely to take place if you have a long draw length.
For these factors, newbies must begin with a longer brace height. It merely prevents a great deal of problems, that are difficult to repair if you’re simply starting.
Last words
Although I advise regularly examining your brace height, it’s unworthy consuming over it. When the brace height modifications, it will likewise alter the arrow’s flight pattern. However if it’s just a couple of millimeters, the modifications will be extremely small.
So do not invest hours playing with your brace height it’s unworthy your time. Simply utilize the suggested brace height and keep it constant. Time invested dealing with your bow is much better invested practicing!
