I caught this one last Saturday night in SW Michigan. This is my first large smallie. We were poorly prepared to catch anything of this size and had no scale and/or tape measure with us. My father-in-law was with me and is a carpenter by trade (knows his measurements) - He guesses this fish would have been 5 lbs, but you know how they always look bigger when you first catch them (adrenaline, etc...). We both agreed that this is a 20" fish, but I would like some of you guys who have caught bigger ones to share what your guess would be of the weight of this one.

Thanks for your input!

Looks around 4 to me. Great smallie!

Awesome fish probably around 4-5 lbs depending on girth

I haven't fished for smallmouth in awhile makes want to get back into it

4+, probably close to 4 1/2.  Nice fish.  

Absolutely beautiful smallmouth.  I would have to guess around 4 to 4.5 pounds, which is an excellent smallmouth no matter where you are!!

Nice catching!

Yeah thats around 4lbs!! Nice fish!!

3.5 lbs

Seriously doubt twenty inches as well, looks closer to 18.

Sorry,  not being a hater, but I've caught and weighed ALOT of fish that size.

Nice fish either way, and I love the pic! The mashed up cigar is a nice touch.

Let's see.

She looks about 18 inches long and a total of 14 inches grith.

So.....

18 X 18 X 14 = 3.78

       1200

If you can give us the length from the photo and then estimate the grith you can use the above formula to estimate the weight.

And that is a beautiful smallie.

Good job!  

Thanks for the kind words! This is my PB SM. I caught a largie at 20.5" and 14.25" girth - that weighed in at 5lbs 14 oz. That is my PB. Big fish for Northern Illinois.

I could see how you might think the fish is shorter than 20", but we know the length was 20" - For a frame of reference, I am not a small guy - 6' - 230 lbs with broad shoulders. I do a lot of shore fishing and have measured from my fingertips to the inside crease of my left elbow and that is 18" - this fish was 19.5 - 20"...

That smallie looks to be around 4 pounds to me, given your size as a background.  Congrats.  

I'd say 3-1/2 to 3-3/4lbs

Nice Fish!!!!!

To give you an example click on my name on my avatar

That fish was a little over 19inches, and was 4lbs on the nose

Pics are deceiving but scales don't lie, LOL ;D

To give you a frame of reference, here are (in order) a 4-0, 4-4, 4-8 and 5-0. I'm sure you will be able to tell which one yours is closest in size to.

4-0

4-4

4-8

5-0

Nice catch, congrats. And best of luck with your replica mount.

I guess 3lbs. 11oz. Great fish...nice job!!! I caught a 2lb. 11oz. smallie the other day (my PB) in a pond not really known for smallies. Great fish........Congrats!!!

Thanks for keeping it real guys! I really appreciate all of the feedback. I am still on the quest for a 5lb+ smallie!

3 - 3 1/2 lbs

Nice fish!

8-)

Cast all doubt aside and buy a scale. Nice smallie.

id say 4-4.5 great fish

im normally very good at this i say 3.12

I would guess a 4 pounder is real close.Nice fish bud.

I'm thinking around four to four and a half.  Nice fish!

3.5 lbs

Seriously doubt twenty inches as well, looks closer to 18.

Sorry, not being a hater, but I've caught and weighed ALOT of fish that size.

Nice fish either way, and I love the pic! The mashed up cigar is a nice touch.

Ya I would agree with that and that is on the heavy side.

Nice fish.  Here's a 5-7

nice fish but from that pic. it IS NOT 20 inches more like 17-18

3 - 3 1/2 pounds

Its a goodun'

I have no idea on the size of it but that is one beautiful  smallie! Congrats to you.  ;D
