Understanding Model Kit Scale Sizes: What Do 1:350, 1:1000, and 1:2500 Actually Mean?
🛠️ Understanding Model Kit Scale Sizes: What Do 1:350, 1:1000, and 1:2500 Actually Mean?
If you've ever been confused by terms like 1:350 scale or 1:1000 scale on model kits — you're not alone. These numbers are more than just random figures on a box — they determine how big or small your model will be compared to the real thing. And when it comes to sci-fi ships, where there isn't a real thing, it gets even more interesting.
In this guide, we’ll break down what model kit scales actually mean, how they affect your builds, and which ones are best for lighting, painting, and displaying.

⚖️ What Does "Scale" Mean in Model Kits?
The scale of a model kit tells you how much smaller the model is compared to the real-life version — even if that “real” version is fictional.
1:1 scale means the model is full-size (like a real prop or set piece).
1:1000 scale means the model is 1,000 times smaller than the original.
1:350 scale means the model is 1/350th the size of the original.
So, a 1:350 Enterprise is much larger than a 1:1000 Enterprise, even though both represent the same ship.

📏 Common Star Trek Model Kit Scales Compared
Scale Example Kit Approx. Length Detail Level Good for Lighting?
1:2500 AMT TOS Enterprise ~4 to 5 inches Basic ⚠️ Limited space
1:1000 Polar Lights NX-01, TOS Enterprise ~11–13 inches Medium ✅ Yes
1:537 AMT Refit Enterprise (Classic Kit) ~22 inches Good ✅ Yes
1:350 Polar Lights Refit or TOS Enterprise ~32–36 inches Excellent ✅✅✅ Ideal
1:100 Studio-scale models or custom Huge! Ultra detailed 🚧 Expert-only territory
Note: Sizes vary based on the original design and the ship’s "real" length in-universe. The Enterprise-D is massive compared to the Defiant, for example.

🚀 Why Scale Matters for Sci-Fi Model Builders
Choosing the right scale depends on what you want from the build:
Display Size: Want a centerpiece for your shelf? Go 1:350 or larger.
Time & Complexity: Just want a quick weekend build? Go 1:1000 or 1:2500.
Lighting Possibilities: The larger the scale, the more room you have for lighting kits, wiring, sound FX, etc.
Cost & Storage: Larger models = higher cost and more shelf space needed.

🔌 Lighting & Electronics: Bigger is Better
If you're planning to add lights (which we definitely recommend for sci-fi kits!), scale really matters.
1:2500 kits are often too small to wire effectively — though we’ve seen some incredible microscale lighting done with fiber optics and micro SMDs.
1:1000 kits are a sweet spot — affordable, decent size, and lighting-friendly.
1:350 kits are the gold standard for lighting: there's room to hide LEDs, wiring, sound boards, even remote control systems.

🧰 Choosing the Right Scale for You
Goal Recommended Scale
First-time builder 1:1000 or snap-together 1:2500 kits

👁️ Visual Example: Enterprise Models by Scale
Imagine the TOS Enterprise in three different scales side-by-side:
1:2500 – the size of your hand (approx. 5–6 inches)
1:1000 – the size of your forearm (11–13 inches)
1:350 – the size of your whole arm (around 3 feet long!)
We’ll be adding side-by-side comparison photos to this blog post soon, so stay tuned!
