Bar length sets the diameter of timber a saw can cut safely in one pass, and a saw should be chosen slightly longer than the largest log rather than exactly at it. Cutting from both sides with a short bar is where most chainsaw accidents start. Bar length is also what decides how heavy the saw feels at the end of an outstretched arm.
Power source then decides where and for how long. Petrol saws at 25.4cc to 52cc go anywhere and run all day on fuel. Corded saws at 1800W and 2200W are lighter and quieter with no fuel or fumes, at the cost of a lead. Cordless saws suit short jobs away from a supply.
Engine size scales with bar length rather than being independent of it. A 25.4cc engine drives a 250mm bar and a 52cc engine drives a 500mm bar, and a long bar on an underpowered engine bogs in the cut rather than cutting slowly. Draper hold petrol saws at 25.4cc, 45cc, 51cc and 52cc across bar lengths from 250mm to 500mm.
Pole saw heads put a short bar at the end of a pole so branches are cut from the ground rather than from a ladder, which removes the most dangerous part of the job. Chain and bar are consumables and are matched to the machine.
