Factorio Blueprint Guides — Ratios, Layouts & Optimization
Use this hub to jump straight to the Factorio bottleneck you need to fix: 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.

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.
// start with your bottleneck
Pick the next guide fast
If your factory is starving for blue science, start with 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, 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.
Once oil and smelting are stable, use the circuit production guide to connect copper, plastic, and assembler counts into one cleaner electronics block.
