Plan the wall. Check the details.
Start with the decision in front of you. Each guide explains a different part of measuring or ordering, with examples you can open in the calculator.
FIELD GUIDE / 01
Concrete block sizes: choose the installed face.
Choose the module that belongs in your calculation, with a diagram of the face and thickness.
FIELD GUIDE / 02Subtract doors and windows without counting them twice.
Measure rough openings, handle repeated windows and understand what an area deduction leaves out.
FIELD GUIDE / 03How many concrete blocks per square foot?
Check the 1.125 factor, compare wall areas and keep base quantities separate from order allowances.
FIELD GUIDE / 04Turn a block count into a supplier order.
Separate the estimated blocks from whole-pallet quantities, leftover units and material costs.
One wall calculator, clear assumptions.
These guides use the same area model as the main tool. They do not specify structural design or a block-by-block layout. Read the complete calculation method before using an estimate to discuss your order.
