Factorio Blueprint Guides — Ratios, Layouts & Optimization
Use this hub to jump straight to the Factorio bottleneck you need to fix: megabases, Space Age planets, oil, trains, science, smelting, or circuits. Every card is a plain anchor link into a dedicated guide so the whole cluster is easy to crawl and easy to use.

9 live resources
Factorio Ratio Calculator
Calculate production rates, assembler counts, belt requirements, and power draw for iron, copper, circuits, and starter science.
Megabase Blueprints for 1000+ SPM
Compare bus, main bus, and city block designs with throughput metrics, UPS notes, power draw, and footprint targets.
Fulgora, Gleba & Vulcanus Blueprints
Plan planet-specific Space Age layouts for scrap sorting, freshness loops, molten metals, and DLC constraints.
Oil Processing & Cracking Ratios
Balance refineries, cracking, and downstream petroleum products so plastic, sulfur, and lubricant stay stable.
Train Networks & Station Blueprints
Standardize 1-2 and 1-4 stations, stackers, and rail loading patterns that scale from outposts to megabases.
Science Pack Production Ratios
Lock in red, green, and blue science blocks with the assembler counts and dependencies that keep labs fed.
Iron, Copper & Steel Smelting Ratios
Plan furnace arrays that saturate belts cleanly and feed early-to-mid game iron, copper, and steel demand.
Green, Red & Blue Circuit Production
Map the copper, plastic, and assembler ratios behind scalable circuit blueprints for electronics-heavy factories.
Green Circuit Array — 900/min
Copy the featured electronic-circuit blueprint string with inline copper cable production, stats, and import steps.

If your factory is starving for blue science, first size the build with the Factorio ratio calculator and then move into science pack production ratios and then check oil processing and cracking so your plastic, sulfur, and petroleum math stays aligned.
If the base is expanding beyond a bus, compare megabase blueprint architectures first, then move into train networks and station blueprints to standardize outposts and unloading. If raw plate throughput is the problem, go straight to the smelting ratios guide for furnace counts, belt targets, and starter array planning.
For DLC builds, use the Space Age blueprints guide before importing old Nauvis layouts onto Fulgora, Gleba, or Vulcanus. Once oil and smelting are stable, use the circuit production guide to connect copper, plastic, and assembler counts into one cleaner electronics block, or copy the weekly green circuit array blueprint when you need an importable 900/min electronics block immediately.
