Kinda late and all, but here goes:
the chunky 19 and 20" bass I've been pulling in this year have all weighed between 3.75 and 4.75 lbs. There's also a formula you can use even without girth to get a really rough estimate of weight. It's length cube divided by...welll....somethingorother.
Anyway, hope this helps a bit.

Here's a handy and very accurate chart courtesy of the Texas Parks and Wildlife:

Estimating Weight of Largemouth Bass

3.5 lbs.

Good find on the chart Cthulhu.
So if the fish is between 19.5 and 20 in, she is a little shy of the 5lb mark, but... add .75 to 1.25lb for the eggs she was packing I still say she was probably a little over 5

I showed the pictures to a Nebraska game and parks warden at the lake the other day. Sorry I don't rember his name but he drives a silver 07 or 08 Ford F-150. He said it was it was a five pounder maybe a little more. He was going off the ones that they had shocked up for a fish censue and it was the time of the year when they spawn. They are also trying to figure out way they have balck crappie in the lake When they never put in any in it when the lake got redone five to six years ago. Anyways he said I could get a master angler award. It has to be a certian size or a certian weight and have a witness sign the form. You also can show them your picture and you can get one also but thats on your word with hardly any facts. He said if I took or sent the picture in to their office I could get the award (most lakes here are total catch and release on large mouth some do have a 21" min. to be able to keep one). I am not going to take the picture in to get the award. I want the fished weighed by them or with them their to get a true award for it. So their is no question in my mind that it was worthy. Their is to much I didn't do to get the picture right and I was to lazy and forgetful to change batteries in the scale. So thats why when I show people the picture. I say I caught a 4 1/2lb. to 5 1/4lb. bass. Anyway you look at it their still nice fish.

No arguments there!
Beautiful fish!
It's not about numbers and records.
It's about appreciating the beauty of quality fish in the open air.

Don't get me wrong, not trying to knock anyone's opinion, just trying to help King find a good close estimate. I'd take fish like that all day any day. I agree, it is all about appreciation of the sport and the beauty of the creatures, but it is nice to stick a good one.

I just found something out. I have been looking at others pictures of bass from diffrent states and then me and finfever whent fishing (He's from the west coast). He said the Largemouth here are wider, shorter and fatter then the one's he caught out west. The picture's I saw they are longer and thinner. Then I read today that some one caught a 23 inch Largemouth and it weighed four pounds. A 23inch bass here would be 7 to 7.5 pounds here. My buddy caught one two weeks ago in a farm pond that was 7.8 pounds and was 23 1/4 long. So does every part of the US have diffrent shape largemouth?

I would think so, just like here, our Redfish are thicker than anywhere else in the country. So they are heavier for length, exceptionally heavier in some instances. Our bass here are short , thick, wide and heavy, just don't get as large as in the big lakes with the FLorida strain.

I just did that Texas site lenght/weight chart, and was almost dead on with a 7lb bass I caught here. Was 22 1/2" long and 7 lbs on the dot, it said 6.89 lbs.

While a large mouth is a large mouth, I believe there are several different strains across the country. For years, I have heard Florida strain large mouth bass got larger than most other strains; while I was in Texas in the early and mid 1990s all the big buzz was about the introduction of Florida strain large mouth coming to Texas.

I know there are several different strains of musky and in southern IL, a strain from Minnesota was introduced when a few new dams were used to create a few man-made lakes. They grow huge in the waters of southern IL, but the summer heat makes them hands-off Jun - Aug.
