I purchased what i thought was 1/4” plywood from homedepot but turns out its actually 3/16”. Is this stiff enough for a drawer bottom? Its 16” wide x 11” long.

If your intention was 1/4” to begin with, then 3/16” would probably be fine. But double check that it is 3/16” before you commit yourself to using it

Plywood typically is undersized and may vary from manufacturer to manufacturer
1/4 is actually 15/32”
1/2 is actually 31/64”
3/4 is actually 23/32”

Keep that in mind when you groove your drawer for the bottom

11×16 no problem.
16×36 problem.

You can add support stretches under the dado for larger drawers as well. We use that size all the time. If you want really nice source 1/4” baltic birch for a little extra strength, thickness, stability, and much more consistent look. It is what we use on our top level cabinet line.

What you likely have is 5.2mm.

“Ply” is unclear. A lot of 5.2 is veneer over an MDF core. Some of the “1/4 inch” family is plies of veneers.

That said, even the MDF core will be fine. Two ways to add strength, if you’re wanting to store your collection of priceless vintage anvils in there, are (a) glue the bottom in the dado, and (2) double the material by gluing a second piece on the bottom. No need to enlarge the dado, just cut it to fit and glue it in after the drawer is assembled. You could invert the drawer and clamp the sistered piece by placing oh, say, an anvil on it.

If you ever come across a piece of plywood that is actually 1/4”, frame it, cause it’s rare. Whether 3/16” is adequate for your drawer depends entirely upon what you intend to put in it.
