Wall Dimensions
What is a Brick Calculator?
A Brick Calculator is a construction estimation tool that helps determine the number of bricks and amount of mortar required for building walls. By inputting wall dimensions, brick size, and mortar joint thickness, you can accurately estimate material quantities, reducing waste and ensuring you order the right amount for your masonry project.
Common Brick Sizes
- Standard Brick (190×57×90mm): The most common brick size in the UK and many countries. Also known as work brick or building brick.
- Modular Brick (194×57×92mm): Designed to be compatible with modular building systems. Slightly larger than standard bricks.
- Queen Brick (244×70×92mm): Longer and taller than standard bricks, used for aesthetic purposes and faster construction.
- King Brick (244×76×92mm): The largest common brick size, often used for feature walls and modern construction.
Calculation Formulas
Number of Bricks:
Bricks = (Wall Area / Brick Area with Mortar) × (1 + Waste %)
Mortar Volume:
Mortar Volume = Total Volume - (Number of Bricks × Brick Volume)
Tips for Using Brick Calculator
- Standard mortar joint thickness is typically 10mm (3/8 inch)
- Add 5-10% waste allowance for breakage, cutting, and future repairs
- Double brick walls use approximately twice the number of bricks
- Account for door and window openings by reducing the wall area
- Different brick bonds (stretcher, Flemish, English) may affect brick count
- Always verify brick dimensions with your supplier as sizes can vary
- Consider ordering slightly more mortar as it's better to have excess
