White crappie are close relatives of black crappie but tend to be slightly longer and leaner. This white crappie length-to-weight chart gives average weights you can use right at the water — especially useful when you’re trying to decide if your fish meets a slot limit or a tournament minimum.
White crappie length-to-weight chart
These figures use weight (lb) = length cubed divided by 1,800 (length in inches), which reflects white crappie’s slightly leaner body compared to black crappie and matches published fisheries data well.
| Length | Average weight |
|---|---|
| 8″ | 0.28 lb |
| 9″ | 0.41 lb |
| 10″ | 0.56 lb |
| 11″ | 0.74 lb |
| 12″ | 0.96 lb |
| 13″ | 1.22 lb |
| 14″ | 1.52 lb |
| 15″ | 1.88 lb |
White crappie vs. black crappie weight
At the same length, black crappie are typically heavier than white crappie because they have a deeper, more rounded body. The difference isn’t dramatic — a few tenths of a pound at most — but it’s enough that you should use the right chart for the right species. If you’re unsure which you have: black crappie have a pattern of scattered spots, while white crappie have vertical bars on their sides and tend to be slightly paler.
Why your fish may weigh more or less
A chart can only show an average. White crappie from highly productive, well-managed lakes run heavier than the table suggests; fish from crowded or low-fertility waters run lean. Seasonal factors matter too — crappie bulk up before the spawn and are among the heaviest they’ll be all year in early spring. After spawning, they tend to slim down until midsummer feeding picks back up.
