   Proceed step by step, moving the block to each subsequent riser. For each riser, place the block on the tread and against the riser. If the current tread height doesn't align with any previous mark on the block, make a new mark. You should now have multiple marks on your block, representing all the different riser heights encountered. Once you have checked all risers (down to the very bottom step), use a measuring tape or ruler to find the maximum difference between any two marks on your block. This measurement represents the overall riser height variation across your staircase.
