Bulbs, clips and strands for 60 ft, by bulb type
Sixty feet takes in a long front eave, or a shorter eave plus a rising gable line. The counts include 10% extra for corners, gaps and a spare, and assume 25 ft strands. The number of bulbs sets the number of clips, because each bulb usually gets its own clip.
| Bulb type and spacing | Bulbs | Clips | 25 ft strands |
|---|---|---|---|
| Mini lights, 4 in apart | 198 | 198 | 3 |
| C6, 6 in apart | 132 | 132 | 3 |
| C7 or C9, 12 in apart | 66 | 66 | 3 |
| C9, 15 in apart | 53 | 53 | 3 |
Strands needed by strand length
Strand lengths vary by brand and bulb type, so check the box. These are the strands for 60 ft with no spare, with 10% spare (our recommendation) and with 20% spare for a roofline with many corners and peaks.
| Strand length | No spare | 10% spare | 20% spare |
|---|---|---|---|
| 17 ft strands | 4 | 4 | 5 |
| 25 ft strands | 3 | 3 | 3 |
| 33 ft strands | 2 | 2 | 3 |
| 50 ft strands | 2 | 2 | 2 |
Planning the 60 ft run
At 60 ft, plan the outlet first: start the run at the end nearest the outdoor outlet so the 3 strands connect end to end without a long cord. Check the box for how many strands may be connected end to end before you buy.
Plug outdoor lights into a GFCI-protected outdoor outlet and use outdoor-rated cords and a timer. LED strands draw a fraction of the power of incandescent ones, which is why many more of them can be linked. For the tree, use the tree lights calculator, and the Christmas lights guide covers the whole house.

Frequently asked questions
How many Christmas lights do I need for a 60 ft roofline?
With C7 or C9 bulbs 12 in apart and 10% extra for corners and a spare, a 60 ft roofline needs 66 bulbs, which is 3 strands of 25 ft. Mini lights 4 in apart need 198 bulbs along the same line.
How many light clips for 60 ft of roofline?
One clip per bulb: 66 clips for C9 bulbs 12 in apart, or 53 at 15 in spacing. Buy clips that match your gutter or shingles, and never staple through the wire.
How many strands of lights for 60 ft?
3 strands of 25 ft, including 10% extra. With 50 ft strands it is 2. Lights follow corners and gable peaks, so measure along the line the lights will take rather than the straight wall.
How many light strands can one outdoor outlet run?
A 15 A circuit should carry no more than 1,440 W of continuous load, and a 20 A circuit 1,920 W. Add up the watts printed on each box, and use the circuit load calculator if you are combining strands with other decorations.
