How many feet of caulk in a tube?
A standard 10.1 fl oz tube of caulk runs about 30.9 feet at a 1/4 in bead. At 3/16 in, DAP rates the same tube at 55 feet; at 3/8 in it runs only about 14 feet.
How far one tube goes at this bead
- Bead: π × (0.25 in ÷ 2)² · one 10.1 fl oz tube ÷ bead = 30.9 ft per tube
- 30 ft × 1.1 extra ÷ 30.9 ft = 1.07 → 2 tubes
There is no single answer, because the bead decides it. The one manufacturer figure to anchor on is DAP’s: its 10.1 fl oz Alex Plus cartridge runs 55 linear feet at a 3/16 in bead. Everything else follows from the volume in the tube and the size of the bead you lay.

How far one tube goes, by bead size
| Bead | One tube runs | Tubes to buy |
|---|---|---|
| 1/8 in | 124 ft | 1 tube |
| 3/16 in | 55 ft | 1 tube |
| 1/4 in | 30.9 ft | 2 tubes |
| 3/8 in | 13.8 ft | 3 tubes |
| 1/2 in | 7.74 ft | 5 tubes |
Feet of caulk per tube, by bead
- 1/8 in bead: about 124 ft. Hairline gaps along trim and baseboards.
- 3/16 in: about 55 ft. DAP’s rated figure; the usual bead for trim and window casings.
- 1/4 in: about 31 ft. Tub and shower joints, exterior window perimeters.
- 3/8 in: about 14 ft. Wide gaps, siding corners; consider backer rod.
- 1/2 in: about 7.7 ft. The widest joint DAP’s data sheet allows without backer rod.
Doubling the bead diameter quarters the yield, because the cross-section grows with the square of the diameter. That is why a sloppy, oversized bead empties tubes so fast. A 5.5 fl oz cartridge holds a little over half as much (DAP: 30 ft at 3/16 in); a 2.8 fl oz squeeze tube about a quarter.
For whole jobs see how many tubes of caulk for a bathtub and how many tubes of caulk per window. Trim gaps before painting are usually 1/8–3/16 in: the baseboards of a 12 × 12 room (about 45 ft, top edge only) take about one tube at 3/16 in. The paint for the same trim is on how much paint for baseboards.
