Specifically you can make them at least 12 inches in height.
It s best to pour the concrete footings thick when building mortared stone walls.
Align the 2 inch wide by 10 inch long 5 08 cm wide by 25 4 cm long boards to build the forms for your footings.
Use an iron rake to push the concrete around as necessary.
This creates 4 straight lines 1 for each side of your wall.
Start the concrete footing by digging the area of the wall a few inches below the frost line the maximum depth in the ground below which the soil does not freeze during the winter consult a structural engineer to design the footing including where to install the vertical reinforcement which usually is placed.
