Gunpla Grades Explained: HG, RG, MG, PG and SD
Bandai sells Gundam model kits in several “grades.” Here is what each grade means, how they differ in size and difficulty, and which one suits a first build.
Gunpla — short for “Gundam plastic model” — is sold by Bandai Spirits in distinct product lines called grades. The grade tells you the scale, the level of detail, and roughly how difficult the kit is to build. Knowing the grades is the single most useful thing for a newcomer, because two kits of the same robot can be very different products depending on their grade.
Entry Grade (EG)
Entry Grade is 1/144 scale and designed to be built without tools or glue. Parts are multi-colored so you can get a clean-looking result straight from the runners. It is the most beginner-friendly line.
High Grade (HG)
High Grade is also 1/144 scale and is the most widely available line, covering a huge range of mobile suits from across the various series. Detail and articulation are good for the size, and most builds are approachable for beginners while still satisfying for experienced builders.
Real Grade (RG)
Real Grade packs Master Grade-level detail into a 1/144 body. It uses a pre-assembled inner frame and many small parts, so it is more intricate — rewarding, but usually not recommended as a very first kit.
Master Grade (MG)
Master Grade is 1/100 scale and features a full inner frame, extensive detail and strong articulation. Builds take longer and have many parts, which is exactly what many hobbyists are looking for.
Perfect Grade (PG)
Perfect Grade is 1/60 scale — the largest and most complex mainstream line, often with internal LED options and highly detailed frames. These are premium, long builds aimed at dedicated builders.
SD (Super Deformed)
SD kits are non-scale, stylized “chibi” proportions with big heads and small bodies. They are quick, fun builds and a low-pressure way to try Gunpla.
Which grade should a beginner pick?
For a first build, Entry Grade or High Grade is the usual advice: affordable, quick, and forgiving. Move up to Real Grade or Master Grade once you enjoy the process and want more detail. Grade names are consistent across series, so once you understand them you can shop confidently for any mobile suit.
