The “standard” yoga mat dimensions are 2 feet wide by 6 feet long. However, this doesn’t mean large mats are not available. You can get some that measure to 7 feet long and 3 feet wide. There are also 6 ft square mats.
It depends on your height and width. If you are over 6 feet tall and weigh over 180 lbs, the standard mat size will be too small. Your head or feet will stick out. Thickness is also important. If the mat is too thin, your knees and buttocks will get hurt. Some people put towels under their knees, but it is better to just buy a thicker mat.
The standard yoga mat dimensions are an eighth of an inch thick. Many people find this is too thin and uncomfortable. Others are so thick they look like beds. The drawback with these mats is they can be difficult to balance on. A very thick mat makes it hard to balance. What you need is a mat that is comfortable but allows you to balance.
Many of the high-end types are 1/4 of an inch thick. These mats may be more expensive, but if your weight goes though a thin mat, this will be necessary. The thick mats are also ideal for yoga practitioners with arthritis. If you practice complex asanas, a thicker mat is advisable.
More about Sizes
You can have a yoga mat custom made if you cannot find the right size. However, this will be more expensive. If you are practicing in a studio, you have to ask permission first. You need to make certain the mat will fit in.
Shorter mats are suitable for kids. The longer mats are ideal for tall persons. The wide mats are recommended for crowded classes. They are also used to keep the whole body on the mat.
Do not use a general all-purpose exercise mat. They are not made for yoga and will not be comfortable. They lack the firmness and comfort required for the asanas. Do not use inexpensive PVC mats either; they are unhealthy.
Another feature you may want is the non-slip surface. If you are always on the go, the weight will be critical. Some mats weigh less than a pound.
The yoga mat dimensions aside, the material used should also be considered. Some are constructed from natural rubber. Others are made from cotton canvas.
