I did the following:

Took a string to measure the seat post and came up with 3 inches.

Convert to MM is 76.19999MM

Divide by 3.14....

And get 24.19 MM in diameter.

Isn't that an odd size? What is the best solution to get the longest seat post possible? This is an old simple hybrid bike so I'd like to keep the cost cheap as possible

I bet it's a standard 27.2mm... Measuring with a string is not the most accurate, then using inches and converting to metric... well, just a lot of opportunities of error...

Longest seat post will depend on many things... The seat post itself, so are designed with the additional strength needed for a longer post, your weight, the heavier you are the shorter you want the seat post, and finally how much post you need in the frame....

... Although it can be a 25mm post which a bit less common, but not unheard of (Trek used that on some of the tri bikes only a handful of years back)

Maybe I should just go get it measured. Ugh. I ended up buying just a simple beater bike that is probably a size 54. A bit too small since I'm 6'1" and usually ride a 58. I figured jacking the seat up a bit more would make it more bareable. Figure not too bad since its literally used to just go to the pool and back.
