Realm Size Value

Realm Size Value is a Realm Management value determined by roughly how much area the realm occupies, in square miles. Note that a realm's raw size only allows you to add more things to an empty realm--owning the entire Antarctic doesn't mean much if no one lives there--or no one can!

The formula is (ln(2*Area) / ln(10)) * 3 = Size as Area = e^(ln(10)*Size/3)/2^[1] This simplifies to log(2*Area)*3 = Size^[2]

This table lists the actual size values as notes. As with Size one goes with the closest integer.^[3]

Realm Size Value	Area (in square miles)	Examples
0	0.5 or lower	Vatican City (109 acres; 0.170313 mi²)^{[note 1]}
1	1.1	Monaco (499 acres; 0.779687 mi²)
2	2.3
3	5.0
4	10.8
5	23.2
6^{[note 2]}	50	Liechtenstein (61.78 mi²)^{[note 3]}
7	108
8	232	Singapore (281.2 mi²)^{[note 4]}
9	500	Hong Kong (427 mi²)^{[note 5]}
10	1,077	Luxembourg (998 mi²)^{[note 6]}
11	2,321
12	5,000	Jamaica (4,244 mi²}^{[note 7]}
13	10,772
14	23,208	Denmark (16,577 mi²) ^{[note 8]}
15	50,000	South Korea (38,691 mi²)^{[note 9]}

23	23,207,944	Krypton^{[note 15]}
24	50,000,000	Earth (land area); Mars
(+0.5)	$x\sqrt[12]{100}$ or x * ~1.467799

Notes[]

↑ Below 0.5 the formula produces negative values which is why Vatican City gets a value of -1
↑ Floods usually only get this large. Above this size, only part of the realm is affected. (see p.39)
↑ Actual size value is ~6.276
↑ Actual size value is ~8.250
↑ Actual size value is ~8.79
↑ Actual size value is ~9.900
↑ Actual size value is ~11.79
↑ Actual size value is ~13.562. This is for the country not the Danish Realm which includes Greenland kicking it up to 2,220,072 mi² or +19.942 which rounds to +20
↑ Actual size value is ~14.666
↑ Actual size value is ~15.796
↑ Actual size value is ~17.0896
↑ Actual size value is ~20.641
↑ Actual size value is ~21.36
↑ Actual size value is ~22.4

Krypton as depicted in Action #500 (Oct 1979) pg 31

Krypton has had so much variation that how this could be figured is unknown. For example, Krypton in Action 500 pg 31 is shown far larger than Earth.
