how many bags of concrete in a yard

June 27, 2026

You can think of it this way: 1 cubic yard of concrete is 27 cubic feet, and each bag only gives you a fraction of a cubic foot once mixed. For most common bag sizes, a good rule of thumb is:

40 lb bags → about 90 bags per yard

50 lb bags → about 72 bags per yard

60 lb bags → about 60 bags per yard

80 lb bags → about 45 bags per yard

20 kg bags → about 82 bags per yard

So if someone asks “how many bags of concrete in a yard?”, they’re usually pouring with 60 lb or 80 lb bags, which means:

Around 60 bags of 60 lb mix for 1 cubic yard

Around 45 bags of 80 lb mix for 1 cubic yard

Quick Scoop

A cubic yard sounds small, but it’s a lot of concrete to mix by hand. You’re turning dry powder into about 27 cubic feet of wet mix, and that takes many small bags to get there. The exact number depends on the bag size stamped on the sack.

These values line up with practical guides and contractor-style calculators that list 60 bags of 60 lb mix or 45 bags of 80 lb mix for a full yard.

How to estimate for your project

Figure out your volume in cubic yards
- Measure length, width, and thickness in feet.
- Multiply to get cubic feet, then divide by 27 to convert to yards.
Multiply by the “bags per yard” for your bag size
- Example: 0.5 yd³ with 60 lb bags → 0.5 × 60 ≈ 30 bags.

 * Example: 0.75 yd³ with 80 lb bags → 0.75 × 45 ≈ 34 bags.

Add a little extra
- Most pros add 5–10% more to cover spillage, uneven ground, or slightly deeper sections.

Forum-style tip

People on DIY and contractor forums often say that once you get close to 2 cubic yards, mixing bags becomes exhausting, because you’d be looking at roughly 120 bags of 60 lb mix or about 90 bags of 80 lb mix. At that point, many switch to ordering a truck from a ready-mix plant instead.
