An artificial tree is a convenient alternative to a fresh-cut Christmas tree for those who don't have the time to go hunting for a real tree and to vacuum up pine needles every couple of days. In order to determine if an artificial Christmas tree will fit where you plan to put it in your home, you must first measure the tree. Learn how to get accurate measurements of an artificial tree's height and diameter so that you know exactly how much space the tree requires.
Things You'll Need
Assemble the main "trunk" of the tree -- the pole that all the branches snap into. Put together the tree's stand and put the trunk in it so that you get the full height of the tree as it stands.
Measure the height of the tree with tape measure, starting at the top of the tree and going down to the floor. Use a stepstool, if necessary, to reach the top of the tree.
Assemble at least the bottom row of branches of the tree by snapping in that row branches and fluffing them out.
Hold the tape measure under the bottom row of branches and measure the distance from one side of the tree to the other, going right through the center, to obtain the diameter of the widest part of the tree.
If the bottom branches are not the longest branches, assemble the row of longest branches and use it to measure the diameter of the widest part of the tree.
