Fifteen feet a tube
The calculator counts a standard tube of cold-pour filler at about 15 linear feet (4.6 m) of hairline to 1/4 inch (6 mm) crack, and rounds up to whole tubes. Read backwards, seven tubes fill about 105 feet (32 m). A larger cartridge, a squeeze bottle or a pail of pourable filler covers a different distance, and the count moves in direct proportion; a wider or deeper crack takes more per foot.
Short cracks cost more
Length is one lumped number, so twenty short cracks and one continuous run of the same total return the same count, though every separate crack costs a start, a stop and a fresh trigger pull. Nothing is added for filler that skins over in a part-used tube between sessions, a bead run past the end of a crack, a clogged nozzle, or filler that slumps as it sets and wants topping up.
Cracks, not failed areas
Only linear cracking is counted. Alligatored or spiderweb areas, potholes and crumbling edges hold far more crack per square foot than a walked-off length suggests and are normally cut out and patched rather than filled, so keep their footprint out of the length. Preparation — routing or wire-brushing the crack open, blowing out dirt, clearing weeds — changes how much filler each crack will take.
How the answer is worked
Nothing here is a second formula. The Asphalt Crack Filler Calculator runs forwards — a size in, a quantity out — and this page grows its own starting crack in proportion until the quantity it asks for is what you have. Where it rounds up to whole containers, the answer is the largest size before the next one would be needed.
Where the calculator adds an allowance for cuts or breakage when you order, the same allowance comes off here, because it is the same calculator: a stack you already own finishes less than its face value. Where it adds none, neither does this page — the settings beside the answer say which.

Frequently asked questions
- How much crack does 7 tubes of asphalt crack filler cover?
- At the Asphalt Crack Filler Calculator's own settings: Enough for 105 ft of crack. That is about 1 crack of the size the calculator opens on: 98 ft of crack. Every figure follows the settings, which you can change in the calculator.
- How many feet does a tube of crack filler cover?
- About 15 linear feet (4.6 m) of hairline to 1/4 inch (6 mm) crack for a standard cold-pour tube, the calculator's figure. Wider or deeper cracks take more per foot, and the label gives the widest crack the product is meant to fill; past that, a different product or a patch is the repair.
- How many tubes of crack filler for a driveway?
- Walk the cracks, add up their lengths and divide by about 15 feet a tube. 100 feet (30.5 m) of cracking is 6.7, so 7 tubes, with the last tube's surplus the only spare. Add a tube where the cracks are many and short, since each start and stop wastes some filler.
- Should I fill alligator cracks with crack filler?
- Not usually. Alligatored or spiderweb areas hold far more crack per square foot than their length suggests and are normally cut out and patched instead. The calculator counts linear cracks only, so leave those areas out of the length and price them as patches.
