How much does #5 rebar weigh per foot?
#5 rebar weighs 1.043 pounds per foot (1.552 kg per metre), so a 20 foot stick weighs 20.9 pounds.
How to work it out
- #5 (⅝ in, metric #16): 1.043 lb/ft
- 20 ft × 1 = 20 ft × 1.043 lb/ft = 20.9 lb
#5 is ⅝ inch in nominal diameter, metric #16. It is heavier than it looks next to #4: about 56% more steel per foot, because weight goes with the square of the diameter.

#5 rebar by number of 20 ft sticks
| Number of bars | Total weight | Total length |
|---|---|---|

| 5 | 104.3 lb | 100 ft |
| 10 | 208.6 lb | 200 ft |
| 25 | 521.5 lb | 500 ft |

Why #5 is so much heavier than #4
A ⅝ in bar is only ⅛ in bigger across than a ½ in bar, but its area is 0.31 sq in against 0.20 — the square of 5/4 is about 1.56. Weight follows area, so 1.043 lb/ft against 0.668. That matters when you swap sizes: changing a footing from #4 to #5 bars at the same count adds over half again to the steel order.
Fifty 20 ft sticks of #5 weigh 1,043 lb, just over half a ton — beyond the payload of many small pickups once you add a person and tools. Ask the supplier to deliver, or split the load.
Cutting and bending #5
Hand cutter-benders rated for #5 exist but take real effort; a grinder or a portable band saw is quicker for a lot of cuts. Wear eye protection. For #4 figures, see how much does #4 rebar weigh per foot, and for the lightest common bar, how much does #3 rebar weigh per foot.
