Mattress size disagreements: where published charts differ
Published bed size charts agree closely on everyday sizes and disagree most on RV sizes. Across 37 pages, an RV King is printed as six different sizes (70 to 72 in wide, 74 to 84 in long) and an RV Queen is 60 × 80 in on 8 pages but 60 × 75 in on 3. The UK Double is 135 × 190 cm on 13 of 14 pages, yet all 11 pages that also print an imperial size give 4ft 6in × 6ft 3in, which is 137.2 × 190.5 cm, 2.2 cm wider.
Our compilation
Every size name, and how far the pages differ
Each row compares what 37 pages from 33 publishers print for one size name. Ranges use the unit each page leads with: inches on US pages, centimetres on UK and French pages. A gap under 1 cm is usually one inch figure rounded two ways. The table shows every figure anyway; nothing is averaged, and no page is treated as the standard.

Read 30 September 2026. Inches are converted at 2.54 cm per inch to 0.1 cm (our arithmetic); the gap is the larger of the width range and the length range. "Most common figure" counts pages that print that figure anywhere on the page. Sizes that only one page prints are listed under single-source sizes, with no range.
UK Double: 135 × 190 cm on the label, 137.2 × 190.5 cm in feet and inches
The 11 pages that print both a metric and an imperial Double all print two different widths. The imperial name, 4ft 6in × 6ft 3in, converts exactly to 137.2 × 190.5 cm, so a mattress sold as 135 × 190 cm is 2.2 cm narrower and 0.5 cm shorter than the size in its name. The National Bed Federation says as much on its own guide: "Bed sizes are not standardised and even if they have the same name (e.g. King size) they may not be the same".

Two other prints stand apart. Dreams prints 53 × 75 in in its inches column on the same row as 4'6" × 6'3" (that is 134.6 × 190.5 cm against 137.2 × 190.5 cm), and Tom's Guide gives the UK Double as 138 × 190 cm. One more page, Crazy Price Beds, prints "46 inches wide x 63 inches long" in an imperial column; we read that as 4ft 6in and 6ft 3in with the marks dropped (inferred), so it is kept out of every range.

Our compilation
RV sizes: one name, several beds
RV names are not standard, and the 10 pages that list an RV King give it six sizes. The most common, 72 × 80 in, is printed by 10 of them, but 10 pages that list an RV Queen split between 60 × 80 in and 60 × 75 in: the same name on a bed 5 inches shorter. Buy by the measurements of the platform, not the name.
One page's own two lists are compared on RV mattress sizes; this page adds the other 9 RV pages and counts them.
US Twin and Full: an inch either way
A US Twin is 38 in wide on 13 pages and 39 in on 2 (Target and Sleep Foundation's single-versus-twin page, which says "38 inches by 75 inches (sometimes 39 inches by 75 inches)"); two UK retailers' tables of US sizes print 98 and 99 cm. A US Full is 54 in wide on 10 pages and 53 in on 5, with 136 and 137 cm on UK retailers' tables, and its length is 75 in on most pages and 74 in, or 74½ in, on others. Serta's table, headed "ISPA Dimension Standard", lists finished mattresses half an inch under the nominal length: Twin 38 × 74½, Full 53 × 74½, Queen 60 × 79½, King 76 × 79½ and California King 72 × 83½ in, each ±½ in.

Continental sizes: the same dimensions under different names
UK pages call 160 × 200 cm a Euro King; French pages call it a Queen; Land of Beds calls it both in one table. 180 × 200 cm is a Super King on the UK pages and a King on the French ones. Because names differ by country and shop, these four sizes are grouped by dimensions instead of by name. The French pages are scoped to France; they are not treated as a European standard.

The word Queen alone sits on three different beds:
- 152.4 × 203.2 cm (60 × 80 in): 14 pages call it a Queen. This is the US Queen.
- 120 × 190 cm (47.2 × 74.8 in): 3 pages call it a Queen. Named by Which?, Dreams, FlexiSpot UK.
- 160 × 200 cm (63 × 78.7 in): 4 pages call it a Queen. Named by Land of Beds, IKEA France, Bultex, Cotesommeil.
The US-versus-UK matches are on UK vs US bed sizes; French sizes on French bed sizes.
9 pages disagree with themselves
On these pages one size name is given two different figures in two places (two tables, or a table and its text). Both are kept.

What makers actually sell
The sizes above are what pages print. These 17 records are the makers' own product pages, from the fixtures behind bed frame dimensions: a US Queen from IKEA is 59⅞ × 79½ in, not 60 × 80. They are kept out of every range.

Method
- Pages. One page is one source. We read 37 pages from 33 publishers: the size guides this site already cites, plus the UK retailer and trade guides, US mattress makers and RV mattress makers found by searching for each size name. Several pages from one publisher count separately, because they can disagree (Sleep Foundation's four do).
- Reading. Each page was re-read on 30 September 2026. We record the name and the figure as printed, in the unit printed; typographic quotes and the multiplication sign are normalised. A script (
scripts/verify-disagreements.mjs) re-reads every URL and checks each printed name and figure is still on the page; all 37 pages passed on 30 September 2026. - Grouping. Rows are grouped by the name a page prints, inside one market. A name is never mapped across markets: a UK Queen, a US Queen and a French Queen are different rows. A UK retailer's table of US sizes counts under the US size it labels. Continental sizes are grouped by dimensions, because their names differ by shop.
- Units. Inches and feet and inches are converted at 2.54 cm per inch and stored to 0.1 cm, as everywhere on this site. That conversion is computed, not sourced, and is labelled so.
- Ranges. A range covers the figures each page prints in its own lead unit (inches for US pages, centimetres for UK and French pages); a page that lists options such as 60 × 74 or 60 × 75 in contributes both. Width-only figures count toward the width range. Product pages, and the six inferred Crazy Price Beds figures, are never counted.
- Units disagree. A page counts as printing two different sizes when its centimetre figure and its own imperial figure differ by more than 1 cm in width or length.
- What was not done. Nothing was measured, averaged or rounded to a standard. A figure is either printed on a page we read or arithmetic on one.

What this page does not cover
- A sample, not the web. These are 37 pages found by search and from the sources this site already cites. Most are written by companies that sell mattresses or bedding. Mattress Firm, Saatva and Helix returned access errors and are not included; Tuft & Needle's size page lists shipping boxes, not mattresses, so it is not used.
- Which page is right. The ranges show what pages print, not what a mattress measures. ISPA calls its US guidelines voluntary, and the NBF says UK sizes are not standardised.
- ISPA itself. The Voluntary Dimensional Guidelines for Bedding is described on ISPA's site but its sizes are not on the page, so the only ISPA-labelled table here is Serta's copy of it. We have not checked that copy against ISPA.
- UK trade bodies. The Sleep Council's site says it is being removed and points to the NBF's Bed Advice UK, whose two guides are included. BedFed's home page carries no size table; its other pages were not read.
- Markets. Only the US, the UK, France and RV pages. Not Germany, Spain, Italy, Canada, Australia or Asia.
- Sizes. Six US sizes, seven UK sizes, four continental widths and eight RV names, plus four single-source UK names. Not Olympic Queen, Full XL, Alaskan or Texas King, split sizes, cot and children's sizes, long variants, or the RV bunk, truck and twin sizes, which pages print as ranges.
- Thickness, frames and bedding. Sizes only. Depth, frame footprints and sheet sizes are on fitted sheet pocket depth, bed frame dimensions and sheet and duvet sizes.
- One reading. Each page was read once, on 30 September 2026. Pages change; the date is on every row.
