Lights for a 4 ft tree, by how full you want it
This is a small tree for an apartment, a porch or a child's bedroom. Pick the fullness you want, then the strand size. Buying fewer, longer strands means fewer connections and plugs.
| Fullness | Lights | Strands of 100 | Strands of 200 | Strands of 300 |
|---|---|---|---|---|
| 50 per foot | 200 | 2 | 1 | 1 |
| 100 per foot | 400 | 4 | 2 | 2 |
| 150 per foot | 600 | 6 | 3 | 2 |
| 200 per foot | 800 | 8 | 4 | 3 |
How many feet of lights for a 4 ft tree
Strands are also sold by lit length. At 100 lights per foot the 400 lights a 4 ft tree needs make 83 ft of string at 2.5 in spacing, 133 ft of string at 4 in spacing, 200 ft of string at 6 in spacing. Wider spacing gives a longer string for the same bulb count, so check the box before you compare prices.
Fitting it under the ceiling
A 4 ft tree needs a ceiling of about 5.0 to 5.5 ft once you add the stand and a topper. See the full Christmas lights guide for a ceiling-to-tree-height chart, and the circuit load calculator to check how many strands one outlet can run.
Power and plugs
400 lights is 4 strands of 100. On LED strands (about 5 W each) that is only 20 watts in total, which is about 1% of a 15 amp circuit's safe load. The same lights in old-style incandescent strands (about 40 W each) draw 160 watts, which is 11% of the circuit, and the strands run hot.
Check the maximum number of strands you can connect end to end: older incandescent sets often allow only 3, which would need 2 outlets or splitters here. Many LED sets allow dozens. See the circuit load calculator if you are also lighting the outside.
