You can always use line to measure with; lay the bass flat and close the mouth, cut a length of line from the tip of the lower jaw to the end of the tail. The girth is around the widest area with the dorsal fin down, cut another piece of line to equal the girth, tie a simple overhand knot in the girth line, save both and measure them when you get home.

Nothing is more accurate than a good scale.

Y'all serious!

That bass would be luckly to break 4#, no girth, compare his hands to the girth.

Maybe he has big hands.

21"r's that are healthy are usually high 4's or low 5's. Your fish looked healthy. 

 

Yup 4.5-5.#

 

6 this time of year needs to be longer.

Those calculators aren't accurate for our area.

You are closer to 4.5lbs, and around here over 4lbs is a mighty fine catch, nice work
