Size Up
Two things on one ground line, drawn to scale: one you know, one you have to size up. How many double-decker buses long is a blue whale? How many Big Bens tall is the Eiffel Tower? The streamer drags the drawing until it looks right. Chat types a number, and chat's guess is the median of every chatter's latest number, the one in the middle. When the timer runs out the real size drops in, and whoever was closer takes the round.

How a round works
- 1
A new object appears
Next to a reference you know, like a bus, a person or Big Ben, standing on the same ground at true scale. Weight and speed rounds ask how many times heavier or faster instead.
- 2
The streamer drags
The blue drawing grows and shrinks with the mouse. A ruler counts in references: ×1, ×2, ×3…
- 3
Chat types a number
2.5 means two and a half times as big. 2,5 and x3 work too, and each chatter's last number counts.
- 4
Chat plays its middle guess
Every guess moves chat's red outline live. By default chat plays the median, so one wild number cannot drag it off; the average is a menu option.
- 5
The reveal
The real size slides in with both guesses on top. Up to 100 points each, the closer side takes the round. About one round in ten is golden and scores double.
What viewers type in chat
2.5 | How many times bigger the new object is than the reference. Decimals with a point or a comma, x3 works too. |
!category weight | Mods: pick a category, or mix for everything. |
!bust on | Mods: no going over. A guess above the answer scores 0. |
!daily on | Mods: play today's Size Up Daily. |
Streamer settings
Drawn to scale
400 drawings with real sizes in 8 categories: towers, landmarks, animals, sea life, dinosaurs, vehicles, aircraft and ships. Two more categories ask for weight and top speed, 458 questions in all.
The median, or the average
Chat does not vote on options: every number counts. The median shrugs off trolls; switch to the average in the menu, or with !median off.
No going over
An optional rule for both sides: a guess above the real answer scores 0. If both go over, the round is a draw.
Size Up Daily
Five rounds, the same objects on every channel that day. Your channel's first Daily of the day counts, and the board shows how your chat ranks among all channels that finished it.
Questions streamers ask
What does chat type?
Just a number: how many of the reference make the new object. 2.5, 2,5 and x3 all work. A viewer can change it any time before the timer ends; only the last number counts.
How is chat's guess calculated?
By default it is the median: every chatter's latest guess, lined up, and the one in the middle. You can switch to the average instead. Guesses past the end of the ruler count as the ruler's end either way.
How are points scored?
100 for an exact guess, falling to 0 at three times too big or too small. Twice too big scores the same as half the size. With no going over on, a guess above the answer scores 0.
How many rounds are there?
1 to 10, 5 by default, with 10 to 120 seconds per object. Mods set them from chat with !rounds and !timer, and !pause stops the clock.
What is the Daily?
Five rounds from all categories, the same objects on every channel that day, with the median and without no going over. Only your channel's first Daily each day counts for the board.
Can the streamer see chat's guess?
Yes, both sides are on screen the whole time. That is part of the fun: follow the crowd or trust your eye.
