# Production Ratios Guide

**Entity Type:** Reference

Production ratios help you optimize supply chains by constructing the right number of production buildings based on how quickly they produce 1 talentum (1t) of goods. This makes your supply chain more efficient and allows you to produce a surplus for trade or expansion.

## Understanding Production Ratios

Production chains work best when buildings are matched by their cycle times:
- **Same cycle time:** 1:1 ratio (e.g., Woodcutter 30s : Sawmill 30s)
- **Different cycle times:** Calculate based on output/input rates
- **Example:** A Tiler takes 60s while Clay Pit takes 30s, so you need 2 Tilers per 1 Clay Pit

These ratios assume baseline production with 100% efficiency, not including the effect of technologies or specialists.

| Olive Oil | 4 Olive Growers (120s) + 3 Olive Presses (90s) |

### Equites Tier

| Good | Production Ratio |
|------|------------------|
| Concrete | 2 Limestone Quarries (30s) + 3 Sand Refineries (45s) + 6 Concrete Mixers (90s) |
| Wine | 2 Vineyards (90s) + 1 Apiary (45s) + 1 Vintner (45s) |
| Cheese | *Cannot be produced in Latium - trade or found a colony in Albion* |
| Togas | 3 Flax Farms (90s) + 3 Snaileries (90s) + 4 Weavers (120s) + 4 Dye Works (120s) + 2 Loom Weaveries (60s) |
| Brooches | *Cannot be produced in Latium - trade or found a colony in Albion* |
| Writing Tablets | 3 Apiaries (45s) + 6 Sandarac Nurseries (90s) + 8 Tabuli (120s) |
| Fine Glass | 3 Mineral Quarries (45s) + 3 Sand Refineries (45s) + 4 Mineral Crushers (60s) + 6 Glass Smelters (90s) + 4 Charcoal Burners (30s) + 8 Glassblowers (120s) |
| Marble | 2 Marble Quarries (60s) + 3 Marble Masons (90s) |

#### Simplified Equites Ratios

The Writing Tablets and Fine Glass production ratios are resource and manpower intensive. Here are practical alternatives for growing cities:

**Writing Tablets (Simplified):**
- 1 Apiary
- 2 Sandarac Nurseries
- 2-3 Tabuli

With 2 Tabuli you overproduce basic resources by 0.34t/min. With 3 you underproduce by 0.17t/min.

**Fine Glassware (Simplified):**
- 1 Mineral Quarry
- 1 Sand Refinery
- 2 Mineral Crushers
- 2 Glass Smelters
- 2 Charcoal Burners
- 3 Glassblowers

This leaves spare Charcoal and excess capacity at your Mineral Crusher but involves far fewer buildings.

### Patricians Tier

| Good | Production Ratio |
|------|------------------|
| Mosaics | 3 Mineral Quarries (45s) + 4 Mineral Crushers (60s) + 2 Clay Pits (30s) + 2 Charcoal Burners (30s) + 8 Tessera Works (120s) |
| Oysters with Caviar | 6 Oyster Beds (90s) + 6 Sturgeon Hatcheries (90s) + 3 Fish Gutters (45s) + 4 Epicures of Water (60s) |
| Bird Tongues in Aspic | *Cannot be produced in Latium - trade or found a colony in Albion* |
| Necklaces* | 4 Gold Washers (240s) + 1 Goldsmith (60s) + 1 Mineral Quarry (45s) + 1 Charcoal Burner (30s) + 2 Jewellers (90s) |
| Cloaks | *Cannot be produced in Latium - trade or found a colony in Albion* |
| Loungers | 3 Apiaries (45s) + 6 Sandarac Nurseries (90s) + 8 Tabuli (120s) |
| Handmirrors | *Cannot be produced in Latium - trade or found a colony in Albion* |
| Lyres* | 4 Gold Washers (240s) + 1 Sheep Farm (30s) + 2 Stringers (90s) + 2 Sandarac Nurseries (90s) + 1 Goldsmith (60s) + 1 Charcoal Burner (30s) + 1 Gilder + 1 Lythier |
| Chariots | *Cannot be produced in Latium - trade or found a colony in Albion* |

*Note: Necklaces and Lyres ratios are not 100% efficient because a perfect ratio requires more Gold Washers than are typically available. Both are balanced around enough output for 1t instead of a perfectly efficient ratio. You can share resources between the 2 chains to make this more efficient, or unlock Mercury-Lugus in the Hall of Fame, then increase your devotion to build Gold Mines.*

## Military Building Ratios

| Good | Production Ratio |
|------|------------------|
| Rope | 1 Hemp Farm (60s) + 2 Ropemakers (120s) |
| Sails | 1 Sheep Farm (30s) + 3 Sailmakers (90s) |

### Simplified Military Production

Making fully efficient military production chains is very resource intensive. In most cases, a simplified approach works better:

**Basic Weapons Setup:**
- 1 Iron Mine
- 1 Furnace
- 1 Weaponsmith
- 1 Charcoal Burner

**Adding Armour Production:**
- Add 1 Furnace, 1 Armourer, and 1 Charcoal Burner to your existing setup
- Hybridize the Leather portion with your Sandal Makers
- Example: 1 Pig Farm and 1 Salt Ponds can supply 2 Sandal Makers + 1 Armourer with some leftovers

---

## Hybrid Production Chains

Sometimes maximizing limited resources (like mines or river slots) to produce multiple goods is more efficient than 100% efficiency on a single chain.

### Example: Tiles + Amphorae Hybrid

The Clay Pit produces 1t of clay per 30 seconds. Both the Potter and Tiler take 60s to produce 1t of goods. This allows:

| Building | Count | Cycle Time |
|----------|-------|------------|
| Clay Pit | 1 | 30s |
| Charcoal Burner | 1 | 30s |
| Resin Tapper | 1 | 60s |
| Potter | 1 | 60s |
| Tiler | 1 | 60s |

**Result:** All raw resources consumed to produce 1t of Roof Tiles and 1t of Amphorae per minute.

Look for opportunities to create hybrid supply chains when resources are scarce - it increases production without running out of river slots or incurring extra maintenance costs.
