The Federal Register shed 39% of its pages in 2025 but only 14% of its documents — its output fell far more in length than in count — and 2026 has won back about half the pages

The Federal Register numbers its pages consecutively from the first business day of each calendar year, so the last page printed on any given date is a running odometer of how much the government has published so far that year. We read that odometer at the same cutoff — the last issue on or before Aug. 25 — for each of the last ten years, straight from the Federal Register's own API, and paired it with the exact document counts the API returns for the same Jan. 1–Aug. 25 window. By that cutoff the page count ran 40,666 (2017), 42,984 (2018), 44,535 (2019), 52,420 (2020), 47,540 (2021), 52,430 (2022), 58,440 (2023), 68,242 (2024), 41,501 (2025) and 54,935 (2026). Two readings stand out. 2024 is the decade high. 2025's 41,501 is the second-lowest of the ten — only 2017 printed fewer by this date — a 39% drop from the year before. The document count did not fall nearly as far. Counting every document the Register published in each window — rules, proposed rules, notices and presidential documents — the totals were 18,209 (2023), 18,766 (2024), 16,140 (2025) and 16,949 (2026). From 2024 to 2025 the page count fell 39.2% while the document count fell 14.0%; the pages behind each document dropped from 3.64 to 2.57, a 29% thinning. The mix did not move: notices were 81.9% of all documents in 2024, 80.7% in 2025 and 80.4% in 2026, so the shorter average is not a swing toward short filings. Underneath, the pieces moved unevenly. Final rules fell from 2,037 in the 2024 window to 1,668 in 2025 (−18.1%), then recovered to 1,947 in 2026. Presidential documents ran the other way — 177 in the 2024 window, then 376 in 2025 (a new-term surge of executive orders and proclamations), back to 176 in 2026 — which propped up the 2025 document total even as rules and notices thinned. In 2026 the page odometer, 54,935, sits about halfway between 2025's floor and 2024's peak, and pages-per-document, at 3.24, has recovered about two-thirds of the length lost the year before.

The following is analysis, not fact. Page count and document count are different instruments, and 2025 is the year they came apart. A notice of a hearing runs a page or two; a major final rule carries a preamble, a response to public comments and a cost-benefit analysis that can run into the hundreds of pages. So the total page count is dominated by the handful of long, consequential rules, while the document count is dominated by the ~81% of filings that are short notices. When pages fall almost three times as fast as documents, the drop is concentrated in the page-dense material — the long rules and their preambles — rather than spread evenly across the short notices that dominate the count. Whether that means fewer big rules or shorter ones, the page odometer and document count alone cannot separate; both would produce this same signature ^sspeculative. Outside trackers that count the narrower slice directly report the same shape: the Competitive Enterprise Institute recorded 68 economically significant rules (those with $100 million-plus in effects) by mid-2025, against 342 in 2023, and the George Washington Regulatory Studies Center's series shows 2024 finishing at a record 106,109 full-year pages before the 2025 reversal [modeled — their tallies, on definitions and windows that differ from ours]. The drop also coincides with a documented administrative act: the Jan. 20, 2025 'Regulatory Freeze Pending Review' memorandum, the kind of government-wide pause every incoming administration since 2001 has issued, designed to delay effective dates and capable of holding down early-year output. That the memo exists and took effect is documented; that it drove this particular 39% drop is an inference we cannot isolate from ordinary first-year deregulatory posture or other factors ^sspeculative. And 2026's rebound is mostly length returning, not a document surge: the document count rose 5.0% while pages rose 32.4%, so the average filing got longer again rather than the government filing far more of them.

Page count is a blunt proxy and it is most of what we measured. A single 500-page rule can swing the odometer more than a thousand routine notices, so a low page count can mean 'no large rules this year' rather than 'less governing' — and it says nothing about the economic weight or burden of what did publish. The George Washington Regulatory Studies Center's longer-run finding cuts the other way from any 'shrinking rulebook' read: across 1995–2020 the number of rules fell while their average length rose, agencies bundling more into fewer, larger rulemakings. Our 2025 snapshot is a deregulatory-year reversal of that trend, not evidence against it. Two more limits. Both endpoints are read at a partial-year Aug. 25 cutoff; full-year 2026 could land anywhere, and cutoff-to-cutoff comparisons carry the noise of blank pages, corrections and issue timing. And pages-per-document across all four document types is a composite — the clean statement is the divergence itself (pages −39% vs documents −14% into 2025), not the ratio, since the ratio can move on the notice/rule mix alone. Every figure here is scoped to the Jan. 1–Aug. 25 window of its year.
