This gateleg table is very old, very heavy. Each leaf hinges out and is supported by a leg that swings out underneath. (It is much sturdier than a drop leaf.)
You can use it with both sides down to save space and yet have a large surface when needed. You can set snug against the wall and open one leaf if that is all you need.
Middle section is 15 inches deep by 41 1/2 inches wide.
Each leaf is 19 inches deep
Full table size is an oval 41 1/2 by 53 inches
28 1/2 inches high
It's a very hard wood with a delicate grain
