Block Fullness Distribution
Distribution of blocks by weight utilization percentage. Shows how many blocks are nearly full vs partially empty
Short ranges plot one point per block, about one every ten minutes. Longer ranges plot one point per day, computed from every block in that day. How it is computed depends on the chart: some average, some total the day up, some are a ratio of the day's sums, and each chart says which. Either way a brief spike inside a day is smoothed away.

About this metric
Definition
How full blocks have been, as a distribution rather than a line. Each bar counts the blocks that landed in a 10% band of the weight limit. Recently almost everything is in the top band: around 97% of the last month's blocks are above 99% of the limit.
How it is measured
A histogram of block fullness. Most modern blocks cluster near 100% because miners maximize fee revenue. Near-empty blocks do occur, and this chart does not establish why: a miner can be working from a coinbase-only template while validating a new tip, and the data shows only the result. On longer ranges that include early Bitcoin history, more blocks appear at lower percentages since demand was much lower.
