Expanded Size Categories[edit]
Size categories are borked. Things are pretty good when it comes to medium sized creatures and things close to medium size, but the larger and larger you get (and vice versa), you start to notice the scaling is off. Things the size of mountains have combat squares barely able to fit a single one of their feet. Monsters with arms made of skyscrapers have the reach of a gnat. It's really messed up.
Attempts at fixing this have been made, from the scaling seen in the Immortal's Handbook to our own attempts, and they work well. There is one small problem with both however; at Huge size and beyond things get different numbers from what currently exists, requiring some alteration when it comes to resizing monsters for gameplay and on maps. It's probably more accurate, but requires a bit of retooling of preexisting material.
While current Colossal and below sizes are technically incorrect, they are not so far up the scale for the problem to be too grievous. With compatibility with preexisting material in mind, I present a size chart which covers the very big and very small, but requires no changes from Fine to Colossal size.
Off The Charts[edit]
Like the Immortal's Handbook and Revised Size, Colossal+ receives a name  Titanic.
Beyond Titanic, the scale repeats, but this time with a prefix; Macro. MacroFine is one size larger than Titanic and two larger than Colossal, or Colossal++ as WotC would put it. MacroDiminutive is three times the size, and so on and so forth. Each time you reach the end, a higher prefix is added as shown below on the Size Category Scales table. This also goes in reverse, starting as Micro and going down.
Size Category Scale  Example 

Yocto  Neutrinos 
Zepto   
Atto  Protons 
Femto  Electromagnetic wavelengths 
Pico  Red blood cells 
Nano  Dust particles 
Micro  Fleas 
Standard  Humanoids 
Macro  Mountains 
Mega  Planets 
Giga  Stars 
Tera  Solar systems 
Peta  Small nebulae 
Exa  Large nebulae 
Zetta  Galaxies 
Yotta  Superclusters 
At Titanic and beyond, and lower than Fine, the scaling changes to match up better with reality. It results in some pretty crazy numbers. After a certain point, creatures like this are more living terrain, or nonexistent threats. After a while, Strength and Size benefits and penalties start evening out as well. The problem of large creatures being unable to carry anything appropriately sized for them is handled separately by listing out the carrying capacity on a different scale for said beings. See the Size Charts below.
Size Charts[edit]
The size charts have been written out below. The extremes are rather unfeasible for actual play, but they're here for the sake of completeness.
