Weight from the 2025 GPC Atlantic Giant OTT table formula. Estimates run about ±5% and assume Atlantic Giant genetics; wall thickness drives heavy-to-chart or light-to-chart and cannot be measured from the outside. Measure the same spots each week for a clean growth curve. Your log saves in this browser and stays on your device.
