Brick size compared
The same wall in every brick size the calculator carries, at this page's area. Modular is the default because it is what most of the country builds with, but a wall specified in king or utility brick needs far fewer units and far less mortar, and the labor drops with the unit count.

What else matters here
A ten by ten wall is 100 square feet of face, which is where most of the searching for this size actually starts. The brick count only cares about that area: lay the same hundred square feet as a long low wall instead of a tall square one and you buy the same 720 brick.
What changes is the course count. Ten feet of height is 46 courses of modular brick, and 46 courses is past the point where a day's lift matters. Mortar carries the weight of everything above it while it is still green, and a wall run too high in one day slumps, squeezes the lower joints and goes out of plumb. Masons cap a day's lift at four or five feet for exactly this reason, so a ten foot wall is two days of laying whatever the brick count says.
Ten feet is also tall enough to need something to stand on. The last three or four feet cannot be laid off the ground, and a plank on two trestles is where a wall this size stops being a weekend job and starts being a scaffold hire.
What this calculator assumes
- Sizes are actual face dimensions, not nominal. A modular brick is 7 5/8 by 2 1/4, and it is the 3/8 joint around it that makes up the nominal 8 by 2 2/3 the coursing is laid out from.
- This is a single wythe, which is what a veneer is. A solid two wythe wall is twice the brick and twice the mortar.
- Mortar is the volume of the bed and head joints across the bed depth of the brick, doubled. The doubling is not a fudge, it lands the bag count on the figure printed on the bag: an 80 pound bag of mortar mix yields about 0.6 cubic feet and lays roughly 37 modular brick.
- Wall ties are one per 2.67 square feet, which is 16 inches horizontally by 24 vertically, the spacing in TMS 402 for anchored veneer.
- Weep holes are one every 33 inches along the base course, which is the usual reading of the 33 inch maximum.
Questions people ask
How many bricks for a 10x10 wall?
720 modular brick. That is 686 for the 100 square feet of wall plus a five percent waste allowance.
How many bricks is 100 square feet?
The same 720, because the brick count depends on the area and not on the shape. A hundred square feet laid long and low takes the same brick as a hundred laid tall and square.
Can a 10 foot wall be laid in one day?
It should not be. Green mortar carries everything above it, so a lift much over four or five feet squeezes the lower joints and pushes the wall out of plumb. Ten feet is two days.
