The directions north, east, south, and west should not be given capital letters unless they form part of a name like West Ham, West Sussex, and South Africa. When used in a name (e.g., North Pole), the word North, East, South, or West is part of a proper noun, and all proper nouns are written with capital letters.
Choose a yoga mat that fits your body and is right for your practice. Mats for the practice of yoga come in a variety of lengths, materials, thicknesses, colors and styles. While there is no set guideline by yoga gurus, the standard size for a mat is 24 inches wide and 68 inches long. However, practitioners should choose a yoga mat based on their preference and comfort level.
I think the pilates mats are a little thicker. Both work just fine for yoga and pilates. The most important thing to factor in when choosing the size of a yoga mat is your body size. 68 x 24 is the standard size for a yoga mat. This size is sufficient for an average height average build person. Over-sized mats are available for taller/bigger yogis. You'll want the mat to be longer than you are tall so you are not hanging off your mat in reclined postures. If you are 6' tall (72), a 74 long mat will be a better option.
