Unit selection
Count units, then choose the right wall system
Brick, block, veneer, and structural masonry do not use the same material plan.
Brick appearance wall
Best when finish quality, bond pattern, and face appearance matter as much as unit count.
- •Higher unit count per square foot
- •More visible workmanship
- •Mortar joints shape the look
Layout and waste move fast when openings, corners, and pattern changes enter the job.
Block-first wall
Best when the project is primarily about speed, structure, or a reinforced wall system.
- •Lower unit count
- •Faster field progress
- •Often paired with grout and rebar decisions
If reinforcement matters, the dedicated CMU calculator may fit the question better than generic masonry math.
Labor-and-mortar-sensitive job
Best when the user is really trying to avoid under-ordering mortar, sand, or skilled labor time.
- •Mortar bags become visible
- •Joint style affects finishing time
- •Openings change waste quickly
The labor plan can matter more than the raw brick or block count on small projects.
Why this section helps
Use this section to compare brick, block, labor, and mortar before you buy.
Fast planning rules
Start with the masonry rules that change the order
Compare unit count, wall type, and mortar demand before you buy.
Standard bricks per sq. ft.
A standard brick wall typically lands around 7 bricks per square foot once 3/8-inch mortar joints are included.
That is why small changes in net wall area can change brick count faster than many DIYers expect.
8x8x16 CMU per sq. ft.
A standard 8x8x16 concrete block wall uses about 1.125 blocks per square foot.
If grout, rebar, and structural details matter too, the dedicated concrete-block calculator is usually the better next step.
Mortar rule of thumb
A common field estimate is about 1 bag of mortar for every 35 to 40 bricks or roughly 8 to 10 blocks.
That rule helps people catch under-order risk before the exact wall layout is finalized.
How to Use This Masonry Calculator
This calculator estimates bricks, blocks, and mortar for your wall project. It calculates mortar, sand, and costs too.
Step 1: Choose Your Masonry Unit
Pick your brick or block type:
Standard Brick (8" x 2.25" x 4")
The classic red clay brick. About 7 bricks per square foot with 3/8" joints. Good for walls, fireplaces, and decorative work. Cost: $0.50-1.00 each.
Modular Brick (7.625" x 2.25" x 3.625")
Slightly smaller than standard. Built for modern modular construction. Same count per square foot. Easier to handle and more consistent.
Concrete Block / CMU (16" x 8" x 8")
The workhorse of construction. About 1.125 blocks per square foot. Use for foundations, retaining walls, and structural walls. Cost: $1.50-3.00 each.
Split Face Block
Decorative CMU with a rough, stone-like texture. Same size as standard CMU. Looks great without extra finishing.
Glass Block (8" x 8" x 4")
Lets light through while keeping privacy. Popular for bathrooms, basements, and accent features. Needs special installation methods.
Step 2: Measure Your Wall
Enter total length and height in feet. For walls with multiple sections, calculate each part or add them together.
Tip: Measure from foundation top to wall top. Don't include cap or coping.
Step 3: Account for Openings
Enter total square feet of doors and windows. This reduces your material estimate. Example: A 3' x 7' door = 21 sq ft. A 3' x 4' window = 12 sq ft.
Understanding Mortar
Mortar bonds masonry units together. Choose the right type for your job:
- Type N - General purpose, medium strength. Best above grade.
- Type S - Higher strength. For load-bearing and below-grade walls.
- Type M - Highest strength. For foundations and heavy loads.
Coverage: One 70-lb bag makes 0.5 cu ft of mortar. That's enough for 35-40 bricks or 8-10 blocks.
Brick & Block Coverage Table
Quick reference for estimating materials per 100 square feet of wall area:
| Unit Type | Size | Units/Sq Ft | Per 100 Sq Ft | Mortar Bags (70-lb) |
|---|---|---|---|---|
| Standard Brick | 8" x 2.25" x 4" | 7.0 | 700 | 18-20 |
| Modular Brick | 7.625" x 2.25" x 3.625" | 6.8 | 680 | 17-19 |
| Queen Brick | 8" x 2.75" x 3.125" | 5.8 | 580 | 15-17 |
| Utility Brick | 12" x 4" x 4" | 4.5 | 450 | 12-14 |
| CMU Block (8") | 16" x 8" x 8" | 1.125 | 113 | 12-14 |
| CMU Block (12") | 16" x 8" x 12" | 1.125 | 113 | 14-16 |
| Split Face Block | 16" x 8" x 8" | 1.125 | 113 | 12-14 |
*Includes 3/8" mortar joints. Add 10% for waste factor.
Mortar Type Selection Guide
| Mortar Type | Strength (PSI) | Best Applications | Cost/Bag |
|---|---|---|---|
| Type N | 750 | Above-grade exterior, interior walls, veneer | $8-12 |
| Type S | 1,800 | Below-grade, retaining walls, load-bearing | $10-14 |
| Type M | 2,500 | Foundations, below-grade heavy loads | $12-16 |
| Type O | 350 | Interior non-load-bearing, repointing | $7-10 |
Wall Types Explained
- Single Wythe - One layer thick. Common for interior walls and non-structural use.
- Double Wythe - Two layers with air space or insulation. Traditional for exterior walls.
- Brick Veneer - Single brick layer on a frame structure. Decorative only, not load-bearing.
- Structural Wall - Load-bearing with reinforcement. Needs engineer approval.
Tips for Accurate Estimating
- Add 10% waste - Covers cutting, breakage, and mistakes
- Check brick sizes - Dimensions vary by manufacturer
- Know local codes - Structural walls have specific requirements
- Plan for scaffolding - Walls over 4 feet need safe platforms
- Watch the weather - Avoid rain, extreme cold, or heat
Cost Factors
Masonry costs vary by material and labor:
| Material | Material Cost/sq ft | Labor Cost/sq ft | Total/sq ft |
|---|---|---|---|
| Standard Brick | $6-10 | $10-15 | $16-25 |
| Concrete Block | $2-4 | $6-10 | $8-14 |
| Split Face Block | $3-5 | $8-12 | $11-17 |
| Glass Block | $25-35 | $20-30 | $45-65 |
What tools do I need for masonry?
Essential tools include: mason's trowel, brick hammer, level (4' and torpedo), mason's line and blocks, joint tool (jointer), mixing tools, and safety equipment (glasses, gloves, dust mask). A wet saw for cutting makes the job much easier.

Masonry FAQ
Brick, block, and mortar questions that affect the wall plan
These questions help users compare unit systems, mortar demand, and DIY-versus-pro decisions instead of treating all masonry walls as the same job.
How many bricks do I need per square foot?
Standard bricks require approximately 7 bricks per square foot (with 3/8" mortar joints). Concrete blocks require approximately 1.125 blocks per square foot. These numbers include mortar joints in the calculation.
How much mortar do I need?
For standard bricks: about 1 bag of mortar per 35-40 bricks. For concrete blocks: about 1 bag per 8-10 blocks. Add 10% extra for waste and learning curve.
Can I lay brick myself?
Basic brick laying is achievable for DIYers with patience and practice. Start with a small project like a garden wall. Structural or load-bearing walls should always be done by a professional mason.
What tools do I need for masonry?
Essential tools include: mason's trowel, brick hammer, level (4' and torpedo), mason's line and blocks, joint tool (jointer), mixing tools, and safety equipment (glasses, gloves, dust mask). A wet saw for cutting makes the job much easier.
What type of mortar should I use?
Type N is general purpose for above-grade walls. Type S is higher strength for load-bearing walls and below grade. Type M is highest strength for foundations and heavy loads. Most residential projects use Type S.
