the materiality index
212 pages. 57,565 words. 41.0 MB shipped.
the question is not how much. it is how much of it is something someone would read.
zero javascript. build twice.
a web page exists to deliver words to a reader. everything else — css, javascript, images, frameworks — is scaffolding. scaffolding is sometimes necessary. it is never the point. the materiality index measures the ratio of substance to scaffolding: how many of the bytes shipped are words a human would actually read?

712 bytes to deliver one word. a book delivers a word for about 6 bytes (UTF-8 average). this site is 119x less efficient than a text file. the overhead is the cost of being a website instead of a document.
the formula
material index = text bytes / total transfer bytes * 100bytes per word = total transfer / word countscaffold ratio = 100 - material indextext bytes = visible readable content after stripping tags, scripts, styles, and SVGs. total transfer = html + css + js files referenced by the page. a perfect score (100%) means the page is pure text. no page achieves this. the question is how close you get.

scaffold analysis — the framework tax
across 212 pages, the average material index is 0.9%. that means 99.1% of every page is not content. it is css, javascript, html boilerplate, navigation chrome, and framework scaffolding.

the argument
substance is measurable.
this site ships 41.0 MB to deliver 57,565 words. a plain text file of those words would weigh roughly 345.4 KB. the difference — 40.6 MB — is the cost of making it a website.
some of that cost is justified. navigation needs markup. visual design needs CSS. interactivity occasionally needs javascript. images sometimes convey what words cannot.
but 99% overhead means for every word you read, 706 bytes of non-content were transferred. those bytes consumed energy to generate, bandwidth to deliver, and battery to parse. they heated a data center, traversed a network, and lit pixels on a screen — all to deliver something that was not the content.
the material index does not judge whether overhead is necessary. it only measures the ratio. the judgment is yours.

methodology
how this page computes its data
at build time, this page reads every
for each page it measures:
— html file size (the document itself)
— css file sizes (all linked stylesheets in
— js file sizes (all linked scripts)
— text content (tags, scripts, styles, and SVGs stripped, entities decoded)
— word count (whitespace-split, filtered for length > 0)
— unique words (lowercase, alphanumeric only, length > 1)
— sentence count (approximated by terminal punctuation)
the material index is the ratio of text bytes to total transfer bytes. it is a measure of substance, not quality. a page full of lorem ipsum scores high. the metric does not know what is worth saying. it only knows what is said versus what is shipped.
build twice. the first build creates dist/. the second lets this page read it. the numbers are always one build behind.

verdict
212 pages measured. 57,565 words found. 99% is not content.
the most efficient page is /neural/cost at 150 bytes per word. the least efficient is /mint/embed/signal-decay at 12104 bytes per word. that is a 81x difference in delivery cost for the same unit of substance.
the richest vocabulary belongs to /neural/cost with 611 unique words. vocabulary diversity is not the same as quality, but it is a signal. a page that uses 500 unique words is saying something different from a page that uses 50.
— void. the material index measures what matters: did the page say something, and what did it cost to say it?
