Murmurs can be classified by seven different characteristics: timing, shape, location, radiation, intensity, pitch and quality. 1  Timing refers to whether the murmur is a systolic or diastolic murmur. 2  Shape refers to the intensity over time; murmurs can be crescendo, decrescendo or crescendo-decrescendo.
Quick Answer. A standard one-car garage ranges in size from 12 by 20 feet to 14 by 22 feet, according to Western Construction. The size can go up to 16 by 22 feet on lots that accommodate the extra space.
Step 1. Measure the length and width of your garage. Multiply them to get the total square footage of the room. An average two-car garage is approximately 484 square feet (22 by 22 feet), but it may range from 400 to nearly 600 square feet.
