how many feet lights for christmas tree

It depends on the size of your tree, but a good rule of thumb is to use one foot of lights per foot of tree height. So, if your tree is 6 feet tall, you should use around 6 feet of lights. Of course, it's also important to consider the width of your tree and the style of lights you're using. For a fuller, more festive look, you may want to use more lights than the recommended amount.
