Decorating a Christmas tree is one of the most exciting parts of the holiday season, but one common question comes up every year: how many feet of Christmas lights do you actually need for a tree? Buying too few lights can leave your tree looking uneven and dull, while buying too many can waste money and create a tangled mess. The good news is that with a little planning, you can easily find the right amount of lights for your tree size and decorating style.
In this guide, we’ll break down how many feet of Christmas lights you need based on tree height, light type, and how full you want your tree to look.
How Many Feet of Christmas Lights Do You Need for a Tree?
General Rule of Thumb for Christmas Tree Lights
A widely used guideline is:
Use about 100 lights (or 10 feet of string lights) per foot of tree height.
This rule works well for standard artificial or natural trees with average branch density. However, it’s only a starting point. Some people prefer a soft glow, while others want a bright, heavily lit tree that sparkles from every angle.
Christmas Light Length by Tree Height
Here’s a simple chart to help you estimate how many feet of lights you’ll need based on your tree’s height:
- 4-foot tree: 40–60 feet of lights
- 5-foot tree: 50–75 feet of lights
- 6-foot tree: 60–90 feet of lights
- 7-foot tree: 70–105 feet of lights
- 8-foot tree: 80–120 feet of lights
- 9-foot tree: 90–135 feet of lights
- 10-foot tree: 100–150 feet of lights
If your tree is very full or wide, you may want to add an extra 10–20 feet of lights for better coverage.
LED Lights vs. Incandescent Lights
The type of lights you choose also affects how many feet you’ll need.
LED Christmas lights
- Brighter than traditional bulbs
- Use less energy
- Often spaced closer together
Because LED lights are brighter, you can sometimes use fewer feet and still get a well-lit tree.
Incandescent Christmas lights
- Softer, warmer glow
- Bulbs are usually spaced farther apart
With incandescent lights, you may need more feet to achieve the same brightness level as LEDs.
Light Density: Minimal, Standard, or Full Coverage
Your decorating style plays a big role in how many lights you should use.
Minimal lighting:
- 5–7 feet of lights per foot of tree height
- Best for simple, elegant designs
Standard lighting:
- 8–10 feet of lights per foot of tree height
- Most common and balanced look
Heavy or professional lighting:
- 12–15 feet of lights per foot of tree height
- Creates a bright, full, showroom-style tree
If you love a glowing, dramatic tree, don’t be afraid to add extra strands.

Real Trees vs. Artificial Trees
Real Christmas trees often have uneven branches and gaps, which may require more lights to achieve consistent coverage.
Artificial trees, especially pre-shaped or slim styles, usually need fewer lights because their branches are evenly spaced.
If your artificial tree is very dense, plan for extra lights to reach deeper into the branches.
Tips for Placing Christmas Lights Evenly
- Work your way up from the base of the tree.
- Wrap lights horizontally for even coverage
- Tuck lights slightly inside the branches, not just on the surface
- Plug in lights as you go to check spacing
- Always test light strands before hanging them
If you’re decorating an outdoor tree, make sure the lights are rated for outdoor use and add extra length for the trunk and power source.
Should You Buy Extra Lights?
Yes—buying one extra strand is always a smart idea. It gives you flexibility if a strand stops working or if your tree needs more coverage than expected. Leftover lights can also be used for garlands, wreaths, or other decorations.
Final Thoughts
So, how many feet of Christmas lights do you need for a tree? For most homes, 10 feet of lights per foot of tree height is a reliable guideline. A 6-foot tree usually looks great with 60–90 feet of lights, while larger trees may need 100 feet or more.
By considering your tree size, light type, and decorating style, you can create a beautifully lit Christmas tree that feels festive, warm, and perfectly balanced—without overdoing it.
