Steam Game Trailer Requirements: The Ultimate 2025 Guide for Devs

If you're a game developer planning to launch your game on Steam in 2025, your trailer isn’t just a nice-to-have—it’s the most powerful marketing tool on your store page.

But what exactly does Steam require? And how do you make a trailer that not only meets Steam’s guidelines but also converts viewers into wishlists, installs, and sales?

At Quadral.io, we craft high-performing, gameplay-first trailers designed for Steam audiences. Here’s our Ultimate 2025 Guide to Steam Game Trailer Requirements—with pro tips to make your trailer stand out.

🔧 Why Steam Trailers Matter More Than Ever in 2025

In 2025, the Steam store page algorithm places huge weight on trailer engagement. If your video doesn’t hook viewers, you’ll lose wishlist momentum—and that can seriously hurt your launch.

A killer trailer increases:
✅ Wishlists
✅ Player trust
✅ Conversion rates

That’s why you need to nail both Steam’s rules and the player’s expectations.

📜 Steam’s 2025 Game Trailer Requirements (Official Guidelines)

Before we get into best practices, let’s start with the rules you must follow to get approved by Steam.

✅ Trailer Format Requirements

• MP4 format (recommended codec: H.264)
• Resolution: 1920x1080 (16:9 aspect ratio)
• Frame Rate: 24, 30, or 60 fps
• Length: No hard limit, but 60-90 seconds is ideal (players lose interest fast)

✅ Content Rules

1. No pre-rendered cinematic trailers unless clearly labeled.
   Pro tip: Steam prefers gameplay footage.
2. No logos or intros longer than 5 seconds.
   Get to the gameplay—fast.
3. No offensive or illegal content (violence, nudity, etc., must match your game’s rating).
4. English is preferred, but if you use another language, include subtitles or translations.
5. No misleading footage—what players see is what they should get.

🎯 Our Pro Tips for Making a Steam Trailer That Converts

At Quadral.io, we’ve delivered dozens of Steam trailers for games like Endless Wander, Blast Royale, and more. Here’s how we maximize impact—while staying within Steam’s guidelines.

1️⃣ Start With Gameplay Immediately

Steam users have short attention spans. The first 5 seconds determine whether they’ll keep watching.
🔹 No logos or studio intros upfront
🔹 Jump straight into gameplay highlights
🔹 Show player actions, not cutscenes

2️⃣ Keep It Short and Focused

Steam players scan trailers looking for one thing:
💡 “Why should I play this game?”

Aim for 60-90 seconds, unless your game needs more. Keep the focus on:

• Core gameplay loops
• Game mechanics
• What makes your game different

3️⃣ Highlight the Genre Clearly

Steam’s algorithms and players both rely on genre clarity.
Show footage that instantly tells players:

• Is it a roguelike, survival, shooter, or cozy sim?
• What’s the pace?
• Is it solo, PvP, or multiplayer?

Use text overlays sparingly to label key features (but don’t overdo it).

4️⃣ Use Clean, Authentic Footage (No Cinematics)

Steam wants real gameplay, not cinematic fluff.
At Quadral, we focus on:

• Player perspective recordings
• Minimal UI clutter
• Avoiding cinematic camera angles that don’t exist in-game

If it’s not part of the gameplay experience, don’t show it.

5️⃣ Sound Design and Music Matter

• In-game sounds make your trailer feel authentic
• Sound effects (reloads, hits, crafting) bring gameplay to life
• Music should enhance pacing but never overpower gameplay audio
• Match soundtrack beats to gameplay moments for maximum impact

6️⃣ End With a Clear Call to Action (CTA)

Your trailer’s job? Drive wishlists.
Always close with:
✅ Wishlist Now
✅ Coming to Early Access / Full Release Date
✅ Demo Available Now (if relevant)

Make sure the CTA appears in the last 10 seconds, with clear, readable text.
