How to measure inseam and outseam?
You'll need to measure your inseam and outseam to make the garment properly. The inseam is measured right from the crotch where the pan ts will be comfortable—that's based on customer preference—down to the bottom of the foot. If you're wearing shoes, it would be down to the top of the sole of your shoe. To take the outseam, it should go from the top of the waistband down to the top of the sole of the shoe or the bottom of the foot.
Where is the inseam measured?
Inseam leg length is measured from crotch to floor, where your true leg length is measured from the top of your legs to your ankles. For more accurate results, ask a friend to help you. If you don’t have someone able to help you, you can take your own measurements. Steps.
How to measure distance from floor to top of object?

Why is one leg shorter than the other?
Having 1 leg that's shorter than the other can be caused by many different things, such as an injury or a bone malformation. Most commonly, a shorter leg is called a structural discrepancy and occurs because 1 femur (thigh bone) or 1 tibia (shin bone) is shorter in one leg than it is in the other.

How do you find the hypotenuse of a triangle?
The main feature of a right triangle is that it should have one 90-degree angle. The hypotenuse refers to the side right across the right angle, and this side also happens to be the triangle’s longest side. Since the hypotenuse is the longest side, it’s easy to find by using various methods. You can use this Pythagorean calculator to find the hypotenuse, or you can follow these steps to perform the calculation manually:
What is the proof of Pythagorean theorem?
In any case, the proof credited to Pythagoras is extremely simple and is commonly known as the proof by rearrangement. Picture two squares and within them, picture four identical triangles. The only difference you would see between these two squares is the arrangement of the triangles within them. Therefore, this means that the space within the squares has an area that’s equal. Equating the area of this space would yield the Pythagorean theorem.
