I have a bag of 6" Renegade brand worms I purchased from Wal Mart. What is a good overall size hook to use on these. I was gonna go with a 1/0 Wide gap but thought it might be a little on the small size,in case the fish doesnt get the head of the worm in its mouth. Think I might miss some fish with a hook of that size? Would a bigger hook be better?

A 2/0 hook would be a better bet, in my opinion.

i like to use a 3/0 to 4/0 owner  extra wide gap  ometimes up to 5/0  but i use big hooks but i would think in your case i would start with 3/0  and go from there    if i am wrong some one correct me        i use bigger hooks because i seem to miss more if i use smaller   good luck

Well, I think there are a lot of good reasons to tweak your hook size and I do sometimes, but a "good overall hook size" is a 4/0 EWG Offset Worm Hook.

I throw a 6" Renegade black with silver dust a lot at night, I call it my do nothing worm.  

Since this is a small thin worm I use a Mustad 3/0 Straight Shank Denny Brauer Flipping Hook.

After owning hooks in practically any size I finally settled in two sizes: #1 and 3/0, with those I rig everything.

I use a 1/0 and 2/0 in ponds.

A 2/0 and 3/0 in rivers.

A 3/0 and a 4/0 in lakes.

A 5/0 on baits like the bush hog or large lizzards.

I also use straight shank and EWG hooks for all plastics.

My friend uses a #1 on his Wacky Worm rig and he does great.  I used a gold #1 at the local pond last week and caught a nice 1 and a half pound bass with no problem on a Wacky Worm Senko.

Just make sure you "cross their eyes" when you set your hook.  I think a good hook-set is more important than the size of hook you are using.

For a 6" worm a 3/0 hook size should be good.

Owner 5102 in either 3/0 or 4/0.

For 6" worms I use 2/0 EWGs or 3/0 offset worm hooks (gamakatsu).You could go one size up.

5" worm 3/0 EWG

4" worm 2/0 EWG

When I cut my teeth on fishing (early stone-age), nearly every fishing book listed hook-sizes

according to the species of fish sought, because live bait was far-and-away the most popular lure.

Today however, the angling community is embroiled in a soft-plastic revolution,

where "lure size" plays the major role in determining the best hook-size.

It's not the length that matters, but the "thickness" of the plastic that occupies the hook throat.

A worm is a slender plastic lure, where 2/0 and 3/0 are arguably the most appropriate sizes.

Worms aside though, and to answer the question: "good overall hook-size" I'd definitely go wth 4/0.

I use more 4/0 Gamakatsu Super Line Z-bend hooks than all other sizes combined.

Too, the size and thickness of the hook is an important component of the overall "weight equation".

CAVEAT> You can't change hook-size without changing the fall rate and behavior of the lure.
