All optimal Anno 117 Pax Romana production ratios

In Anno 117 Pax Romana, your city lives and dies depending on how effectively and efficiently you can handle production chains (and some meddling from Rome). The crux of this elusive efficiency lies in production ratios, a rather confounding term that simply refers to the optimal number of production buildings required for a supply chain to run smoothly.

The overall benefit of having optimal production chains is that buildings don’t linger idle waiting for resources, and each one is working at peak efficiency consistently. This, in turn, means a steady flow of goods to sate your denizens and even partake in trade to stock up your coffers with Denarii. In this guide, we’ll walk you through the optimal production ratios for each supply chain in Anno 117 Pax Romana.

✓ VideoGamer Summary

• Production ratios ensure supply chains run at peak efficiency.
• The key is to have the right number of building of each type to ensure there’s no time or surplus materials being produced.
• Ratios differ between Latium and Albion.

Production ratios explained

Put simply, production ratio is the optimal number of buildings of different types in a supply chain to ensure none of them are missing resources and there isn’t a raw material surplus at any time. This ensures the final product in the chain is produced as fast and as efficiently as possible with no downtime. The idea is to consider the processing time of each building to determine the optimal number of each required.

An example is the best way to explain production ratios. A Sheep Farm takes 30 seconds to produce 1t of Sheep, while Pileus Felter takes 60 seconds to produce 1t of Pileus from 1t of Sheep. What this means is that for every 1t of Pileus you produce, you’ll have a surplus of 1t of Sheep. To optimise the Pileus production chain, you’ll want two Pileus Felters using 2t of Sheep to produce 2t of Pileus every 60 seconds. The 1t of Sheep produced every 30 seconds (or 2t every 60 seconds) by the Sheep Farm is therefore used. 

It also works the other way around, where not enough of a raw material is produced to keep up with the production time of buildings further down the supply chain. In other words, ratios let all the buildings in a supply chain keep up with one another’s processing time.

Note that this assumes that you’ve attained and maintained 100% perfect productivity for each building. These ratios are also affected by Specialist buffs and perks as well as research benefits, but as these are so varied and player-dependent, we won’t factor them in here.
