Size It Up: Animals
Size It Up Animals on Sizes.games: Recognising an animal does not tell you how big it is. Compare two animal silhouettes using the dimension named in the question: standing height, shoulder height, body length or another stated span. Resize the target beside the known reference, then check the reveal. Animals has its own five-round Daily game and new five-round comparisons in Unlimited.

Twice the shoulder height
Two shoulder heights compare the ground-to-shoulder spans. A taller head, horn or raised neck does not become part of that measurement just because it appears in the silhouette.

Half the body length
Compare the length specified for each animal. Read the scope to see whether the tail is included; the entire drawing and the measured body span can end at different points.
Animals in the current library
There are 40 animals in this category. The selection includes land mammals, birds and marine animals, with different measured dimensions. These eight introduce the library; their names do not identify today’s five targets.

Shoulder height is not head height
A lion or elephant can be measured to the shoulder, while a giraffe uses a standing-height reference. Follow each label and its endpoints.
Use the reference animal as a ruler
Estimate how many measured reference spans fit into the target’s span. Refine that proportion instead of trying to remember a metre value from a photograph.
How your score adds up
Each guess earns a base score from 0 to 100 by comparing your estimate with the stated reference size. The closer the ratio is to 1, the higher the score. Half-size and double-size guesses earn the same base score.
The five round weights
- Round 1×1
- Round 2×1
- Round 3×2
- Round 4×3
- Round 5×3
For example, 80 base points in a ×3 round contribute 240 points. Five perfect rounds total 1,000.

What the measurement includes
Animal measurements are published reference values, not exact measurements of the individual in the drawing. Sex, age and body position can affect real sizes. A round names the measured dimension and any relevant scope, such as shoulder height or body length. Scores use that stated reference. The silhouette keeps a recognisable shape; its full outline can extend beyond the measuring endpoints.

Questions about Size It Up: Animals on Sizes.games
Do I need an account for Animals?
No. Animals progress and Daily results stay in this browser when storage is available. Use the same browser, category and mode to return to a game.
Can I play more animals after the Daily?
Yes. Switch to Animals Unlimited for new five-round games from this category. Your completed Daily result stays locked; Unlimited does not replace it.
Why do some animals use shoulder height?
The question follows the dimension in the published reference. Shoulder height stops at the shoulder, while standing height can extend to the highest named point. Read the labels for both animals rather than comparing every visible pixel.
Are all animals of a species the same size?
No. Individuals vary. The game uses the stated published reference value, with its scope and approximation notes, so every player is comparing against the same basis for that round.
Does an animal’s tail count?
It depends on the stated measurement. A body-length reference may use different endpoints from a full silhouette. Check the scope and measuring line before guessing, then inspect the source after the reveal.
Can Animals include a building as the reference?
No. An Animals game uses two animals. Choose Mixed for compatible comparisons drawn from different categories, or explore Landmarks for structures.
