Games Like Size It Up
About Games Like Size It Up
The Size It Up game is a daily size-guessing game from Magnitudle. Each round sets a target object beside a familiar reference, and you resize the target until it looks the right size next to it, then lock in your guess to see how close you were. A day is five comparisons, each worth up to 100 points, and there are themed editions for pop culture and geography. The fun is in finding out how far off your sense of scale can be, and how good it feels when the reveal lands right on your guess.
The games on this page test the same sense in other ways: which of two real things is bigger, how many things you saw in a glance, where exactly half of a shape is, and how real things compare in size, distance and age. They are our own games, not versions of Size It Up, and Gamefinity is not affiliated with Magnitudle. All are free in your browser on a phone or a computer, with no download and no sign-up. Loomlarge, How Many and Rank It are among our Daily Games, the same for everyone, so you also see how today's players guessed; Halfway is a daily too, ten shapes a day for everyone. The table below says what each one shares with Size It Up and what is different.
Each pick next to Size It Up
All four show the true answer the moment you commit. How Many, Halfway and Rank It score you by how close you came; Loomlarge scores a right call, its speed and your streak.
| Game | The guess | What it shares with Size It Up | What's different |
|---|---|---|---|
| Loomlarge | Which of two real things is bigger: taller, longer or wider | Real objects compared at true scale, with the reveal drawn to size | You pick one of two instead of resizing one, and fast calls and streaks score more |
| How Many | How many jelly beans, sheep or stars you saw in a few seconds | Five visual estimates a day, scored by how close you came | You guess a count, typed as a number, and then see the crowd's median guess |
| Halfway | Where one straight cut splits a shape into exact halves, thirds or tenths | Judging size by eye, with the true split shown after every guess | No reference object: you weigh the shape against itself, round after round until three cuts are way off |
| Rank It | The order of five real things by one measure, such as height, area or distance north | Real-world comparisons and a reveal of the true values | You put five things in order rather than sizing one, and the measures go beyond size: calories, dates, latitude |
Call which is bigger
Loomlarge is the nearest to Size It Up in subject: real things at their real sizes. Each round shows two, such as a ship and a tower or a dinosaur and a bus, and asks which is taller, longer or simply bigger. Make your call and both land on one steel tape at true scale, so you see the answer drawn to size, not just a number. The ten pairs a day start easy and close in to a photo finish, and a wrong call never ends your day.
Guess a count at a glance
How Many is the closest in feel. The curtain opens on a jar of jelly beans, a field of sheep or a sky of starlings for a few seconds, then falls, and you type your guess. The judges count every one, and your score depends on how close you came as a ratio, so guessing twice too many is exactly as bad as guessing half. Five exhibits a day climb from about thirty rubber ducks to thousands of stars, the same for everyone, and after each one a chart shows everyone's guesses and the crowd's median, which is often uncannily close.
Judge size by eye
Halfway tests the same eye with no numbers to type. Make one straight cut through a paper shape, a croissant, a hedgehog or the boot of Italy, and the pieces show their share of the area to the decimal. Later rounds ask for a third or a quarter or spin the shape. There are 755 shapes, ten a day, and a perfect cut is worth 1,000 points.
Know how things compare
Rank It is for the part of Size It Up that is knowledge rather than eyesight. Each day brings five lists of five things to put in order by one question, such as most calories or farthest north, and the reveal stamps each with its real value from sources such as NASA, the US Census Bureau and Wikidata. Every list hides at least one surprise, like Buenos Aires lying farther south than Sydney.
How to choose
Pick Loomlarge for the sizes of real things, How Many if you love the guess and the reveal of a visual estimate, Halfway if you want to sharpen your eye with no numbers to type, and Rank It for real-world comparisons beyond size. If you like guessing time and distance as well, Darkroom has you count seconds in your head and GeoDrop scores a pin on a world map by how many kilometers off it lands; more are on the estimation games page.
Frequently asked questions
What are some games like Size It Up?
On Gamefinity: Loomlarge, where you call the bigger of two real things, ten pairs a day; How Many, five counts a day to guess at a glance; Halfway, shapes to cut into exact halves by eye; and Rank It, five lists a day of real things to put in order. All are free in your browser.
Is there an unlimited game like Size It Up?

How do you get better at estimating?
Break the picture up. In How Many, count a small patch and multiply by how many patches fill the jar or the field. In Halfway, look for where the area balances rather than the middle of the outline: a long thin tail holds less paper than it seems.
