Note: Redwood height and volume rankings change occasionally as trees grow, suffer injury, or fall and as updated measurements and new discoveries are published. Rankings shown above reflect last-disclosed dimensions. Largest redwoods are ranked according to main trunk volume (excluding reiterations and branches).
1. Floyd Otter and King Arthur lost significant volume after the 2020 Castle Fire, and Diamond lost significant volume after the 2021 KNP Complex Fire. Pending updated volume estimates, these trees likely no longer rank among the 30 largest giant redwoods.
2. Undisclosed 25,138 ft3 (712 m3) coast redwood in Redwood Experimental Forest.
3. Undisclosed 23,816 ft3 (674 m3) coast redwood on private land.
