A good way to determine which support you should use is by the amount you'd need your guitar raised above your leg while in your seated position.
Measure how much you'd like your guitar lifted above your left leg and then refer to the following guide to select the size of your support:
3.75 to 4.75 inches: Short
4.75 to 7 inches: Standard
5.75 to 9 inches: Tall
The curved arm of all supports can be adjusted from a minimum height of 1.25 inches to a maximum of 2.75 inches.
Sagework guitar supports are symmetrical and work for both right or left-handed players.
