There are several ways to compare the length of the two pieces of yarn. You might cut several pieces of the length of your shorter string, lay them end-to-end next to your longer piece, and count how many you need. Another way is to fold the longer string into equal parts so that the length of the folded string equals the length of the shorter string. The number of folds needed is exactly the number of times your shorter string goes into your longer string.

Ape Index doesn’t seem to impact arm strength and arm speed with what is the ratio of wingspan fingertip to fingertip the correct technique.” The key here is correct technique.

Benefits of Being Proportionate

Emphasizing your extra-long arms can make you more competitive in some sports, or you can focus on your legs and other abilities if you have a shorter wingspan than your height. Leg reach in the UFC is measured from the outside of a fighter’s leg, from the top of the hipbone to the heel. If the measurement is not taken from the outside of the leg, it’s inaccurate.

This small detail of Durant’s body may actually benefit his unstoppable game. While not in the “freakish” category, Dwayne Wade possesses a 6’11” wingspan to compliment his 6’4” frame. These measurements account for a 7.25% wingspan differential that he puts Wade in the “elite” category just below “freakish,” but his impact surpasses that classification. In his career, Wade also has 548 careers blocks in 547 games , the most for any NBA starting guard since 1973 when blocks became a recorded stat. Will Bynum has the same 4” differential in his wingspan (6’0” with roughly a 6’4” wingspan); his differential coming in at 5.3 percent, which measures as “above average” by our metrics.

Measure the Reach

In addition, some people measure these ratios to see if their proportions are within a normal range, or to gauge aesthetics. Enter your wingspan and height into the calculator to determine your wingspan to height ratio, also known as APE index. It is good to remember that these ratios are averages over a large group of people. Some of these variations might even be used as an advantage, like being tall and having exceptionally long arms can be advantages when playing basketball. If you have a negative Ape Index, meaning your arms are shorter than your height, you won’t travel as far in the water with each stroke as someone with a positive index, simply because your reach is shorter. Although his arms are long, Durant’s hand size does not match the rest of his body. In fact, KD claims that he can’t even palm a basketball!

Measure your arm over the shoulder and down your arm. Do not go measure down your back, as you will want to get the fullest arm length possible. Instead, go across your shoulder and down your arms. If you’re not sure how to take this measurement, think about what a long-sleeved shirt seam will look like—this is approximately the length you will measure.

While that 4” is advantageous to Oden as a big man, it is comparatively more advantageous to Bynum because of his length relative to his body at a foot shorter. This equation reflects the length advantage relative to their size as opposed to just their raw length. For example, Greg Oden stands at 7’0” with a 7’4” wingspan, making for a 4” differential that comes in at 4.8 percent greater than his body, which is “average” by our scale. While it might not be the most natural measurement in regards to a player physically, it is the most organic and relevant to the game. From there, we subtracted that number by one to give us the “percentage of wingspan greater than height.” This shows how much longer their wingspan is relative to height. The objective of the present study was to establish multiethnic, all-age prediction equations for estimating stature from arm span in males and females.

The following formula is used to calculate a wingspan to height ratio. To measure the wingspan of each subject we had the subject stretch his/her arms out horizontally or as horizontal as possible. We used no instruments to make sure each arm was straight, in alignment with each other, or horizontal; it was done by eye. It is possible that the wingspan was measured to be shorter than it should be. The head to body ratio is a little more complex as it changes from a ratio of about one to four for a small child to about one to eight for an adult.

Shorter arms when weightlifting gives the athlete less distance when lifting above their heads, and also allows the weights to be closer to their center of gravity. So, although it may seem harder for them at the beginning, they will tend to progress to harder climbs at a faster rate. Plus, how tall someone is will closely correlate to weight, which is why shorter climbers will benefit from a lighter weight, and they tend to keep better body tension on steeper climbs too. It’s easy to think that taller climbers have more of an advantage, with their longer reach and all, but there’s something to be said for shorter climbers, and it’s the way they learn to adapt faster. This data also reflects the idea that men have longer arms relative to their height than women. Only Emily Harrington and Alex Puccio manage to get into the positive zone. And is your arm span and height exactly the same?

Most of the society indeed has similar wingspan and height, but not always. Humanity inspires art, and one mathematically accurate art piece often referenced when it comes to wingspan and height is Leonardo da Vinci’s “Vitruvian Man”. Inspired by Vitruvius’ writing, this drawing shows da Vinci’s perception of the perfect male body.

If you cannot turn your back to a wall, stand up as straight as possible and avoid hunching your shoulders. Taking your measurements over the shoulder and down the hand will give you a precise reading, particularly if you are measuring your arm length for clothing.
