No standard size of ottoman exists. They come in many different shapes and sizes, what can make finding the ideal for a space a little harder The right size depends on the available space and the furniture in the room.
Ottomans have height between 13 and 20 inches. Those of standard size measure 26 to 40 inches and work well as seating for one person or practical footrests. You commonly find them around 40 inches wide and 26 inches deep, what allows you to use them as a coffee table or extra soft seating.
How to Choose the Right Ottoman Size
Square ottoman sizes include 20×20, 24×24, 28×28, 24×36 and 28×36 inches, also.
Choosing the right ottoman size goes beynd looks. It is about use and balance. The right size can do several tasks, for instance give extra seating, serve as a coffee table or simply let you put your feet up.
A strong model even works as a comfortable footstool. For use as a coffee table use a bigger version for drinks and snacks. A strong ottoman tray works well on a storage model.
The ottoman should be the same height as the sofa or a bit lower for best comfort. For instance, a sofa with a 21-inch seat height goes with a 16-inch ottoman. Even a very low sofa of 14.5 inches works with a 16-inch footrest.
Some small ottomans only reach a foot high, much lower than adult seating at 30 to 35 inches. Such models fit the need for a small footrest with a bit of storage.
In modular corner sofas use a square footstool of 30×30 inches, or even 36×36 inches, depending on the number of seats. A smaller size can seem entirely lost. Two square ottomans together give even more flexibility.
If they are big, one between two chairs usually suffices.
The ottoman size regarding the sofa follows the same rules as for a coffee table. A round model sits 12 to 18 inches in front of the sofa. In a narrow room maybe you prefer a 15-inch deep wooden bench as an alternative for an ottoman or coffee table.
A big ottoman holds weight and seats two people comfortably when needed. Many fabric models exist, and some brands offer single and double sizes.
