About This Calculator

Our masonry material estimator calculates the number of bricks or blocks and bags of mortar needed for your wall project. Accurate material estimation prevents costly mid-project delays and ensures you have consistent materials from the same production lot.

The calculator accounts for your chosen unit type (standard bricks or concrete blocks), mortar joint thickness, and wall dimensions. It calculates the number of courses, units per row, and total mortar required, plus a waste factor for cuts and breakage.

This tool is perfect for DIY masons building garden walls, barbecues, or planters, contractors preparing estimates, and anyone asking "how many bricks do I need for a wall?" or "how much mortar for block wall?" Running out of material mid-project is frustrating and expensive.

How to Use This Calculator

Follow these steps to estimate masonry materials:

  1. Enter your wall length and height in feet
  2. Select your unit type (standard brick or 8x8x16 block)
  3. Enter your mortar joint thickness (typically 3/8" for brick)
  4. Review the estimated units and mortar bags needed
  5. Add 5-10% extra for cuts around openings and corners
Frequently Asked Questions

How many bricks do I need per square foot?

Standard modular bricks (2-1/4" x 3-5/8" x 7-5/8") require about 7 bricks per square foot with 3/8" mortar joints. King-size bricks require about 5 per square foot. Concrete blocks (8x8x16) need 1.125 blocks per square foot.

How much mortar do I need for bricks vs blocks?

Bricks require about 3-4 bags (60 lb) of mortar per 100 square feet due to more joints. Blocks need only 1-2 bags per 100 square feet because of fewer, larger joints. Always buy extra - running out mid-project causes visible color variations.

What mortar type should I use?

Type S mortar is best for below-grade applications and retaining walls. Type N is the most common for above-grade exterior walls. Type O is for interior and non-load-bearing walls. Check local codes - some areas require specific types for structural applications.

Do I need rebar in a block wall?

Most block walls over 4 feet tall need vertical rebar every 4 feet, filled with grout. Horizontal rebar (in bond beam blocks) is required every 4 feet of height. Retaining walls need more reinforcement. Always check local codes for specific requirements.

How do I cut bricks and blocks?

For straight cuts, use a diamond blade in a circular saw or angle grinder. For volume work, rent a masonry saw with water cooling. Score and break works for bricks using a brick hammer and chisel. Always wear safety glasses and dust mask.

What is the proper mortar joint thickness?

Standard mortar joint thickness is 3/8" (10mm) for both bricks and blocks. This provides optimal strength and appearance. Thinner joints are stronger but show more variation; thicker joints (1/2") accommodate less precise units but are weaker.
