Want to know how many Christmas ornaments or light strings you need for your tree? How many Christmas lights can you put on one of your circuits without blowing a fuse? Our free Christmas Decoration ToolSet™ will answer these questions and more...Christmas decorating made easy at Santa's Quarters.
*Our Christmas Ornament Calculator™ is based on an average ornament size of 3.5", and assumes coverage that's not too light, but also not too heavy. Be sure to check out our large selection of Christmas ornaments. For commercial Christmas ornaments please use our Commercial Ornament Calculator™.
*Our Christmas Light Calculator™ works for both residential and commercial Christmas trees and lights. The calculation is based on standard 6" mini light spacing or 12" C7/C9 lights. Please see our Christmas lights for all your options.
*Please consult a licensed electrician before you begin any lighting projects. You can find out how many amps your circuit(s) are rated for by looking at the number on your circuit breaker. Most circuits are rated for either 15 or 20 amps. The above calculator assumes 80% of the total capacity for safety. It is also important to know how many outlets are on one circuit. You can determine this by making note of which outlets stop functioning when you switch a circuit off.
*The packaging your lights came in should have either the total watts of the string or the number of bulbs and watts per bulb.
*This tool provides you with the maximum number of light strings you should put on one circuit. It does not tell you how many light strings you can connect together. Generally you should not connect more than three 50' incandescent strings end to end. You can connect a larger number of LED Christmas lights together since they use 90% less power. Please see the packaging on your LED lights for more information.
*The number of watts per bulb should be found on the packaging your lights came in.
*Be sure your light strings and extension cords are rated for sufficient amperage.
