What "size" is my full-suspension bike?
I've read there is a rule of thumb for finding if a bike fits -
This is the full bike:
Here is the seat in it's lowest position (highest = 43"):
And the imprints on the bottom bracket, in case they are useful:
- sit on bike and inseam should be 2" off ground (or, you are just able to stand on your tippy toes!)

Few bikes I ever saw listed on craigslist and elsewhere listed a size. Maybe just measure the seat tube, the max saddle height, effective top tube length and stack. Pic's of each with tape measure might help.
Few buyers will probably know what to do with that though. So don't sweat it.

Take a horizontal line from the top of the head tube/headset to where it intersects with the seatpost. Then measure from this point down to the centre of the bottom bracket. This will be the nominal size of this frame in inches/centimetres.
For the record, I don't believe that this bike is too big for you, based on how much seatpost you have exposed, but if you want to sell it then sell it.

You should not be able to reach the ground while seated. I an 5'8" and my bike saddles are around 38" high if measured from the ground. You should be able to get full leg extension while pedaling seated. You slide off the saddle to reach the ground when stopping. Looking at the headtube and guessing that that bike should be pretty close for you.

if you're going to talk about inseam, you need cycling inseam or actual inseam, not your pants size. look that up. how high is the bottom of your pelvis from the ground when standing in your bare feet. that's a start. I am 5'9" with average proportions and my actual inseam is about 34". my legs might be just a tad on the long size for my heigh. if you're 6' tall with a 30" actual inseam, you might have an undiagnosed medical disorder.
most bicycles have a sticker on the seat tube of the frame that states the frame size. at 6' tall, you should be on a 19-21" frame.
unrelated—that chain needs more than oil. it needs to be replaced. it's way beyond maintenance now.
