Build Orders

A build order is a scripted opening sequence that tells you exactly what to build, in what order, at what supply count. Consistent execution of a build order is the fastest way to climb at any skill level.

What Is a Build Order?

A build order is a sequence of construction actions (workers, buildings, units, upgrades) annotated by supply count at each step. For example: "14 Supply Depot, 16 Barracks, 19 Refinery" means you build a Depot at 14 workers, a Rax at 16, and a Refinery at 19.

Supply counts are used instead of timestamps because game speed settings and actual build decisions compress or expand the timeline. Following supply counts is reproducible regardless of game speed.

Most builds are designed to achieve a specific timing window — a point in time where your army composition, upgrade level, or tech structure lands slightly before your opponent's defences are ready to receive it.

Reading a Build Order

Example: Standard Terran 1-1-1 Opening
Supply Action
14 Supply Depot
16 Barracks
16 Refinery
19 Orbital Command
19 Factory (when Barracks finishes)
20 Supply Depot
21 Reactor on Barracks
22 Starport (when Factory finishes)
22 Tech Lab on Factory
24 Supply Depot + Marine x2

The numbers on the left are supply counts at the time you should begin the construction. When you hit 14 supply, immediately queue a Depot. When it finishes and you're at 16 supply, queue a Barracks — and so on.

Execution Tips

Practice in vs AI

Run the build against an Easy AI with no pressure. Focus entirely on hitting supply counts. Repeat until it's muscle memory before taking it into ranked.

Don't Improvise Early

Deviating during the opening costs timing. If you swap step 3 for something else because you got scouted, your timing will slip. Stick to the build through the first 4 minutes.

Set Reminders

On Terran/Protoss, set up hotkey camera bookmarks at your main production buildings. Glance at supply count every 20 seconds and match it to the next step in the build.
