what is the best size worm to use in inches for big bass?

For targeting the biggest bass, the biggest worm you can find would be a good bet. 11-13 inches is not uncommon for a lot of big bass fishermen.

That being said, a lot are also caught on considerably smaller worms, so to each his own....

i use 10 inch worms  a lot in the summer.a 7 inch will usually catch more fish.

I would have to go along with dodgeguy on that.  6 to 10 inches is what I mainly use.

At least around this neck of the woods, 4-6" worms are the norm -- 3" or less if you are finesse fishing

I fished 7" Senkos for awhile, but all but two of my 10+ have been caught on 6" Senkos.

That would be my suggestion.

All my largest bass were caught on 7 1/2 ring worms  

10" worms

A 10-16 inch.RPM lures makes the 16 inch.

I can't imagine fishing a 16" worm. I only use 3-4". Mostly 3 and I catch a lot of big ones. I don't think the key to catching a big bass is the size but how you use it :-? . I believe that the smaller worms are better because the big bass still go for them and they can take the whole thing in at once, and you don't get any of those missed hits from the bass biting the end of it. This whole paragrah sounds extremely sexual.

The 6-inch worm appears ideal in the north

while the 7-inch worm appears ideal in Florida.

Foot-long worms won't guarantee catching any larger bass,

but they certainly guarantee that you'll catch fewer bass

Stitching a big worm is one of the best ways to catch big bass.

But it takes waaaaayyyyyy to much patience and time for me to do it.

Heck, you can make 40 deadsticking casts with a Senko before you stich a big worm back to the boat.

You can read up on big bass hunting and stitching in Bill Murphy's book "In Pursuit of Giant Bass".  It is a great book for any serious bass fisherman.
