Panel sizes range from 3 to 6 ft. Make sure you take the exact measurements of your space, so you know how many panels you need. Some outdoor bamboo panels require the setting of posts for their installation. As you'll be building a secluded area in your outdoor space, consider how high you want the panels to be. The higher you go, the more privacy you'll get. Of course, you still need to remember the rules and regulations set by the local authorities regarding panel heights.
