Concrete Curb Calculator
Calculate concrete needed for curbs. Estimate cubic yards, bags of concrete mix, and cost for rectangular and L-shaped curbs.
Step 1: Curb Type & Dimensions
Concrete Curb Basics
Standard curb dimensions: 6 inches high × 6 inches wide. Allow 5-10% extra for waste. One cubic yard of concrete covers approximately 40 linear feet of 6×6 inch curb.
Step 2: Calculation Options
Concrete Bag Coverage
40lb bag: ~0.3 cubic feet
60lb bag: ~0.45 cubic feet
80lb bag: ~0.6 cubic feet
Mix ratio: Typically 1:2:3 (cement:sand:gravel)

Cost Saving Tips
1. Order during off-season (late fall to early spring)
2. Combine with other concrete projects for larger order
3. Consider bagged concrete for small projects (< 0.5 yd³)
4. Rent tools instead of buying for one-time use
