What is the difference between HG, RG, and MG Gundam model kits?

Understanding Gundam grades is essential for any builder entering the world of Gunpla (Gundam Plastic Models). Bandai categorizes these model kits by scale and complexity to help builders choose the right project for their skill level.
  • High Grade (HG) — 1/144 Scale (Approx. 13cm tall): This is the most common and versatile category. High Grade kits feature a massive variety of mobile suits from every single anime timeline. They are molded in accurate colors, require no glue or paint, and feature straightforward engineering. If you are a beginner or looking for a clean, quick build, you can browse our authentic HG Gundam 1/144 collection.
  • Real Grade (RG) — 1/144 Scale (Approx. 13cm tall): Do not let the small size fool you. Real Grade kits match the compact footprint of an HG but pack the structural complexity of a much larger kit. They feature an advanced, pre-molded internal skeleton (Advanced MS Joint system) and tiny, realistic decal stickers. They offer incredible articulation and detail for experienced builders who love a challenging build within a smaller display space.
  • Master Grade (MG) — 1/100 Scale (Approx. 18cm tall): Master Grade kits offer a step up in physical presence. At a 1/100 scale, these models allow for highly detailed mechanical inner frames, moving armor pistons, opening cockpits, and intricate detail parts. They take longer to construct but offer unparalleled mechanical realism and look spectacular on a display shelf.
