How to use it
- Enter wall length in feet.
- Enter wall height in feet.
- Enter unit dimensions if different (default 16"×8").
- Read units needed and total area.
The Belgard Wall Calculator lets you input the length and height of any concrete wall and instantly tells you how many 16"×8" units are required and the total square‑foot area. Because each unit is a fixed 16 in × 8 in (1.33 ft × 0.67 ft), the tool multiplies the wall dimensions to get square footage, then divides by the unit’s 0.89 ft² area, rounding up to whole units. Knowing the exact count prevents over‑ordering and saves money, while the area figure helps you estimate material costs and labor. The results appear in two simple numbers: Units needed and Area (sq ft), ready to copy into your project plan or order form. You can also adjust the unit dimensions if you’re using a different block size, and the calculator will instantly recalculate. This makes it ideal for remodels, new builds, or estimating repair patches.
Pro tips
- Add a 5‑10% waste allowance for cuts and breakage.
- Round up to the next whole unit; you can’t order fractions of a block.
- Order a few extra units for future repairs or design changes.
- Double‑check measurements before entering them to avoid costly mistakes.

Case study
Mike needed a 12‑ft by 8‑ft retaining wall. Using the calculator, he saw he required 108 units and 96 sq ft of concrete, ordered exactly that amount, and avoided a $200 over‑order.
