Extension length of plank between sawhorse and step ladder for use as scaffold?

• A. 6"
• B. 12"
• C. 18"
• D. 24"

Answer: (B)

When you set a plank as a makeshift scaffold between a sawhorse and a step ladder, how far the plank overhangs beyond the ladder matters for balance and footing. The safe overhang is about 12 inches. This length gives enough space for your foot to land on solid plank while keeping most of the plank supported by the ladder, which helps prevent tipping and swinging. If the overhang is only 6 inches, you may not have enough room to step safely, increasing the chance of slipping. If the overhang is much longer, like 18 or 24 inches, the lever effect on the ladder grows, making the setup more prone to tipping and movement and creating a higher fall risk. So 12 inches strikes the right balance between stability and usable working space. Ensure the plank is solid and properly supported on both ends, and keep the weight centered during use.
