Unity Build Size Estimator Tool

📦 Are you building a mobile game or WebGL experience in Unity and wondering how big your final build will be? The Unity Build Size Estimator helps you predict your game’s total build size based on the number of textures, models, scripts, audio files, and more—tailored to the platform you’re targeting (Android, iOS, WebGL, or PC).

🎯 Why Build Size Matters in Real Life

Imagine you're an indie developer working on a casual Android puzzle game. You’ve added some nice background music, a few high-res textures, and your app is shaping up well. But when you upload it to the Play Store, you get hit with a warning: APK exceeds 150MB limit.

This is a real pain point for developers—especially for mobile. Larger builds mean:

  • ❌ Slower download/install times for players
  • ❌ Potential rejection from app stores
  • ❌ Poor performance on low-end devices
Using this estimator, you can anticipate such issues *before* packaging the app—and even receive tailored tips to reduce your build size.

🛠️ Tool Features

  • ✅ Estimate size based on asset count (textures, models, scripts, audio, etc.)
  • ✅ Platform-aware calculations: Android, iOS, WebGL, or PC
  • ✅ Real-time feedback and best practice suggestions to reduce size
  • ✅ 100% client-side tool – no data is uploaded or shared

📈 Who Should Use This Tool?

This tool is especially useful for:

  • 👨‍💻 Indie Unity developers shipping to mobile or WebGL
  • 🎓 Game design students learning optimization
  • 📱 Devs preparing to publish on Google Play or the App Store

✅ Example: Build Size for a Mobile Puzzle Game

Let’s say your game has:

  • 🖼️ 30 textures
  • 🎵 5 audio clips
  • 🧱 20 3D models
  • 📜 10 scripts
On Android, the build size might estimate around 75–90MB. With this tool, you’ll instantly get a prediction—and tips like compressing textures or using Addressables to shrink the size by 20–40%.
