What size cobblestones are there?
Several. However, I primarily use ‘Jumbo Belgian Block’ (10″ x 7″ x 4″) for my aprons and regulation size cobbles to edge for many reasons. First, the ‘jumbos’ are the heaviest and largest stones which wear the best under adverse conditions for driveway and barn aprons. They look great and appear proportionate. I use ‘regulation’ (9″ x 7″ x 4″) size cobblestones for my edging. These are tough rectangular stones I set in deep mortar trenches that are much more uniform in width and length than jumbos. I create fantastic serpentine edging to create a natural flowing landscape with existing or future garden beds and borders. They also are perfect straight edging for a linear effect.
