What this site is
You get a black silhouette at a true measurement and a white one to resize. You lock in. The truth is drawn in red, and the score follows the ratio between your guess and that truth. Five rounds make a daily board, shared by anyone on the same local date and the same shelf. Unlimited pairs are for practice. Compare shows two truths at once, with no score. That is the whole product.
The cut-outs are original drawings made for this library. They are not traced from another game and they are not photographs. A drawing is a claim about the axis we named: length, height, width, or area. It is not a portrait and it is not a license to treat the picture as a trademark study. Names of places, ships, towers, and animals are used because the sizes are public facts, not because we claim any brand.
Who operates it
The site is operated as an independent project. There is no user account, no public leaderboard, and no request that you tell us who you are in order to play. Mail about corrections, privacy, or the measurements goes to hello@sizeitup.space. That address is the contact for this project. If you write, say which object and which sentence you are disputing. A note that only says "wrong" cannot be checked.
We do not claim a staff, a studio, or a publisher relationship we do not have. The footer says the same thing the about page says: independent, not affiliated with sizeitup.games. If a directory or a clone lists this game as that site, the directory is wrong. The canonical home of this project is the address in the footer and on the privacy page.
How a number gets into the library
Measurements are rounded public figures: encyclopedias, sports rule books, and manufacturer specifications. Rounding is deliberate. An eye cannot use a millimetre on a whale, and a false precision would pretend the board is a survey. When an object has more than one honest figure, the fact line picks one and says which. The Statue of Liberty includes the pedestal. The Eiffel Tower includes the antennas. Big Ben means Elizabeth Tower. A blue whale is a large adult at 27 metres, not a record claim.
Area and length are stored as different kinds of size and are never paired. Texas on this board is land area, about 696 thousand square kilometres. Metropolitan France is about 552 thousand. Chile's entry is a length, mainland north to south. If you think a figure is the wrong version, write. If you think the drawing's axis does not match the fact, write that too. The library changes by editing the catalog, not by a vote on a comment thread. There is no comment thread.
What we do not do
We do not take bets, sell hints, or run a paid streak. The game is free. We do not ask for a name to save a day. The streak and today's result stay in this browser under a local storage key. Clear the site data and the streak goes with them. That is described again on the privacy page, because it is the main thing the site remembers.
English is the default language. Serbian in Latin script is the second, switched from the header. The puzzles do not change when the language changes. The sentences do. A measurement argument should quote the language you were reading, because a translation can be clumsy even when the number is the same.
Why the game is built this way
Most size arguments on the internet are a caption under a cropped picture. The crop is doing the lying. This board puts two objects on one scale and grades the multiple, so half as big and twice as big are the same kind of miss. Within 6 percent scores 100. Five times off scores 0. Later rounds on a five-round day count more. None of that requires an account, and none of it requires you to trust a stranger's diagram.
If you only remember one instruction from this page, remember the affiliation line. Play the game. Do not treat it as the official site of another game with a similar name. Corrections and privacy requests use the same mailbox. We would rather fix a pedestal than collect a profile. The pages linked from the footer, including privacy, contact, and these terms, are the public identity of the project. They exist so a reader can see who to write to and what the site is for, without guessing from the game alone.
