Typical heights range from about 23 inches up to 41.25 inches. Maximum extended widths vary widely — roughly the low 40-inch range up to about 71 inches, with many models around 50–55 inches.
Most models are hardware-mounted (screwed into the wall or trim). A smaller number of gates use pressure-mount systems as an alternative.

They are designed for doorways, hallways and both top and bottom of stairways. Several models are suitable for indoor or outdoor mounting and can also serve as room dividers.
Yes. Lower-profile examples in the data include heights around 23 inches and others near 30 inches, offering shorter barrier options where needed.
Retractable gates roll up or pack away to save space; when retracted they fold out of the way and do not swing open, so they typically do not block the pathway.
