If you’ve ever been captivated by the world of Gundam, you’ll know the awe that comes from seeing a Gunpla mega size model in person, towering over your display space with unmatched presence. These colossal kits are more than just a building project; they’re works of art that showcase precision, craftsmanship, and a collector’s passion. 

Collectors worldwide, including those shopping at Japan Figure, are eager to secure these impressive kits. But what exactly does “mega size” mean, and why are these models so sought after?

1. What does the Gundam mega size mean?

A Gundam mega size model is typically a 1/48 scale plastic model kit, making it significantly larger than the standard MG (Master Grade) or HG (High Grade) kits. Standing around 37–38 cm tall when completed, these kits are designed for display impact.

Compared to smaller grades like RG (Real Grade) or MG, the mega size offers:

• Larger parts for easier handling and assembly.
• Enhanced visual presence in any collection.
• Impressive detailing without the need for extensive painting.

If you’ve ever wondered what is Gunpla, the mega size range is among the top contenders, rivaled only by gigantic kits like the Perfect Grade Unleashed or colossal special releases.
