Best for their light weight and uncomplicated use for tasks nearer the ground. A shelf holds tools or paint.

But they work only one way and won’t work on stairs. Not as rigid as multiuse ladders. Some may have pinch points at spreader bars.

Price $25 to $250.

Best for versatility. Can be an extension or stepladder, or a scaffold, and can be used on stairs. More rigid than stepladders. Easier to store than conventional extension ladders and better for jobs below 17 feet.

But they’re heavier and pricier than other types and harder to set up. Some taller models can pose safety risks when fully extended.

Price $100 to $500.

Best for projects above 17 feet. These ladders are light for their size, easy to set up, and more rigid than multiuse models when used as a straight ladder.

But extension ladders work only as straight ladders and, unlike multiuse ladders, offer no other configurations. They also require ample storage space.

Price $70 to $250.
