Brick Calculator (USA Standard)

Calculate the number of bricks and mortar bags needed for your masonry project. Uses USA standard brick sizes and includes waste factor calculation.

Wall Length Feet (ft)

Wall Height Feet (ft)

Brick Size Modular (7 5/8 × 2 1/4 × 3 5/8 in) Standard (8 × 2 1/4 × 3 3/4 in) Engineer Brick (7 5/8 × 2 3/4 × 3 5/8 in)

Include 10% waste factor

Material Requirements

Wall Area: 0 sq ft

Bricks Required: 0

Mortar Bags (Type S): 0 bags

* Based on standard USA brick coverage of 6.75 bricks per sq ft. Mortar calculation assumes 3 bags per 100 bricks.

Concrete Calculator (Cubic Yards - USA)

Calculate concrete volume in cubic yards for slabs, footings, or columns. Converts from cubic feet to cubic yards (1 cu yd = 27 cu ft).

Length Feet (ft)

Width Feet (ft)

Depth/Thickness Inches (in) for slab, Feet (ft) for footing/column

Waste Percentage Percent (%) - Extra for spillage, over-excavation

Concrete Requirements

Volume: 0 cu ft

Concrete Needed: 0 cu yd

Bags (80lb) if mixing: 0 bags

* 1 cubic yard = 27 cubic feet. Ready-mix concrete is typically ordered in 1/4 yard increments.

Concrete Block (CMU) Calculator

Calculate the number of standard 8x8x16 inch CMU blocks and mortar required for your project.

Wall Length Feet (ft)

Wall Height Feet (ft)

Include 5% waste factor

CMU Block Requirements

Wall Area: 0 sq ft

Blocks Required: 0

Mortar Bags (Type S): 0 bags

* Based on standard 8x8x16 inch CMU blocks (1.125 blocks per sq ft). Mortar calculation assumes 3 bags per 100 blocks.

Mortar Calculator

Calculate mortar bag requirements based on wall area or brick/block count. Select mortar type for accurate coverage rates.

Mortar Type Type S (General use) Type N (Above grade, exterior) Type M (Below grade, heavy load)

Calculate Based On Wall Area Brick Count Block Count

Wall Area Square Feet (sq ft)

Mortar Requirements

Mortar Type: Type S

Coverage Rate: 40 sq ft/bag

Mortar Bags Required: 0 bags

* Coverage rates vary by mortar type and application. Type S: 40 sq ft per bag, Type N: 45 sq ft per bag, Type M: 35 sq ft per bag.

Rebar Calculator

Calculate rebar requirements for concrete slabs or footings based on spacing and area dimensions.

Area Length Feet (ft)

Area Width Feet (ft)

Rebar Spacing Inches (in) - Typical: 12" for slabs, 6" for footings

Rebar Size (Optional) #3 (3/8") - Light duty #4 (1/2") - Standard slabs #5 (5/8") - Heavy duty #6 (3/4") - Structural

Rebar Requirements

Area Size: 0 sq ft

Rebars Required (Length): 0

Rebars Required (Width): 0

Total Rebar Length: 0 ft

Total Weight (Approx): 0 lbs

* Rebar is typically sold in 20-foot lengths. Weight calculation based on #4 rebar (0.668 lbs/ft).
