how many lights per foot for christmas tree

A general rule of thumb is to use one foot of light strand for every foot of Christmas tree. So if you have a 6-foot tree, you should use 6 feet of lights. However, this is only a guideline and you can use more or fewer lights depending on your personal preference and the size and shape of your tree. If you have a very large tree, you may want to use multiple strands of lights to ensure that every part of the tree is properly illuminated.
