Estimates the US school grade level required to understand the text. Grade 8–10 is typical for mainstream non-fiction; above 16 is graduate-level. Combines average sentence length and average syllables per word.
Estimates years of formal education needed. A score of 12 is readable by a high-school senior; above 17 is considered difficult even for college graduates. Penalises long sentences and words with three or more syllables.
Simple Measure of Gobbledygook. Like Fog, it counts polysyllabic words but uses a simpler formula. Best applied to texts of 30+ sentences; tends to agree closely with FK Grade for academic prose.
Unlike syllable-based metrics, Coleman-Liau uses character counts per word and sentence. Returns a US grade level. More stable across languages and OCR-processed texts; not sensitive to unusual long words with few syllables.
Uses character-to-word ratio and word-to-sentence ratio — no syllable counting needed. Returns a US grade level (1 = kindergarten, 14 = professor). Closely tracks FK Grade in practice.
Based on a list of ~3,000 familiar words known to most 4th graders. Words outside this list are counted as "difficult." A score below 5 is very easy; above 9 is college-level. More sensitive to vocabulary than sentence length.
Originally designed for US Air Force technical manuals. Counts "easy" words (≤2 syllables) vs "hard" words (≥3 syllables). Returns a grade level estimate. Can be erratic on short texts.
The only metric here where a higher score means easier reading. Scores: 90–100 = very easy (children's books); 60–70 = standard prose; 30–50 = academic; below 30 = very difficult. All charts invert this axis so that up/outward always means harder to read.
Each bubble is one custodian. Horizontal = number of entries done; vertical = average words per entry; bubble size = total word output. Reveals who wrote many shorter entries vs. fewer but longer ones.
Five metrics are averaged per custodian, then normalised 0–1 per metric across all custodians: the custodian with the lowest average on a metric scores 0; the highest scores 1. This makes the shape comparable across metrics with very different scales.
Flesch Reading Ease is inverted (relabelled “Flesch Ease (inv.)”) so that all five axes point outward = harder/more complex: a wide polygon means the author tends toward longer, more complex prose; a narrower polygon indicates shorter, more accessible writing.
Did the team write more for must-have entries? Each point is one entry; box shows median & IQR.
Use the dropdown (top-left of chart) to switch readability metric on the y-axis. All metrics: higher y = harder to read. Flesch Reading Ease is axis-inverted so it follows the same convention.
Use the dropdown to switch metric. Box shows median/IQR; points show individual entries. All metrics: higher y = harder to read.
Top 10 hardest (left) and top 10 easiest (right) completed entries by Flesch-Kincaid grade level. Colour = custodian.
Each line is one entry, coloured by custodian. Drag a range on any axis to filter entries; click the axis label to sort. All axes: top = harder/more complex. Flesch Reading Ease axis is inverted so top = hardest, consistent with all other axes. Metrics:
Histogram showing how entry lengths are distributed per custodian. Reveals whether entries cluster tightly or span a wide range.
Word counts for Dedication, Preface, Reader’s Note, Introduction, and Bibliography Introduction — the meta-work surrounding the main encyclopedia entries. Colour = custodian.
Pearson r between pairs of readability metrics (lower triangle). Red = positive correlation, blue = negative.
Average sentence length vs. percentage of difficult words. Longer sentences with more difficult words sit top-right.
All metrics Z-scored per column so colours are comparable across scales. Red = harder / longer, blue = easier / shorter. Entries sorted by Flesch-Kincaid grade (hardest at top).
