I’ll try it here.
Rating these heaviest to lightest how would you list the following?
All will be the same size and 3/4” thick.
1. Birch plywood 2. Melamine 3. MDF
Thank you for your time.

Solid melamine, or melamine faced particle board? If the latter, it’s 3, 1, 2 I think.

Melamine and MDF are pretty close in weight.
About 90 lbs a sheet I think.

Hardwood ply tends to be around 60 lbs give
or take. I’ve bought it with a couple of layers
of 1/8” MDF in it, which makes it more stable
but a little heavier.

Sometimes 5/8” melamine is available which
is lighter. Ultra-light MDF is available too. I
prefer it just because it’s so much lighter but
it seems more prone to warping.

I thought this would be a tough question and it was.
Out of three responses two rated MDF heaviest and two rated Ply as #2. Each material got a vote as the lightest. Melomine was picked 1 2 and 3. Interesting…
I’m planning an extension wing and a drop down outfeed table for my new Ridgid 1245.
With the “improved” three castor system the beast can be tippy even on a smooth surface. Thus the weight concern.
I don’t think a small amount of either material will alter the movement that much.
I have seen 5/8” melomine. That may be the answer.
Again, Thank you for you time.

A little googling will give you some weights, like here

As mentioned, it rather depends on what type of melamine and plywood your looking at.
