Understand the differences between HG, RG, MG, and other Gundam model kit grades to choose the right one for your skill level and collection goals.
Quick Answer
Gundam model kits come in several grades, each with different scale, detail, and complexity. For beginners, High Grade (HG) kits are the best starting point due to their simplicity and affordability. If you want more detail and are willing to invest more time, Real Grade (RG) offers a sweet spot, while Master Grade (MG) provides the most intricate builds for experienced hobbyists.
Walking into the world of Gunpla can be exciting but also overwhelming. With so many acronyms like HG, RG, and MG, it's easy to get confused about what each grade means and which one is right for you. This guide breaks down the major Gundam model kit grades, their key differences, and how to choose based on your skill level and collecting goals.
Whether you're a first-time builder or a seasoned veteran, understanding these grades will help you make informed decisions and avoid disappointment. We'll also look at some specific kits available at The Gundam Galaxy to illustrate the differences in practice.
What Are Gundam Model Kit Grades?
Gundam model kits, often called Gunpla, are categorized into grades that indicate their scale, level of detail, complexity, and price range. The most common grades are High Grade (HG), Real Grade (RG), Master Grade (MG), and Perfect Grade (PG). Each grade offers a different building experience, from quick and simple to highly complex and detailed.
The grade you choose affects not only the final look of your model but also the time and skill required to build it. Beginners often start with HG kits, while more experienced builders might prefer RG or MG. Understanding these differences is key to building a collection that matches your interests and abilities.
- HG: 1/144 scale, simple builds, great for beginners
- RG: 1/144 scale with advanced detail and articulation
- MG: 1/100 scale, larger with more intricate parts
High Grade (HG): The Perfect Starting Point
High Grade kits are typically 1/144 scale, making them compact and affordable. They feature good color separation and articulation, but with fewer parts and simpler assembly. HG kits are ideal for beginners who want to learn the basics of building without feeling overwhelmed. They are also great for expanding a collection quickly without breaking the bank.
For example, the MS-05B Zaku I HG is a classic mobile suit that offers a straightforward building experience. It's a great way to add a piece of Gundam history to your shelf without a huge time commitment. Similarly, the Destiny BB #290 SD is a Super Deformed (SD) kit that's even more compact and cute, perfect for a quick build or as a desk companion.

- Affordable price point, often under $15
- Quick to build, usually 1-2 hours
- Good articulation for dynamic posing
Real Grade (RG): Detail in a Small Package
Real Grade kits are also 1/144 scale but pack in much more detail and engineering. They feature advanced articulation, intricate part separation, and sometimes even inner frames. RG kits are more challenging than HG but offer a rewarding build with a highly detailed final product. They are a great step up for builders who want more complexity without moving to a larger scale.
While we don't have an RG kit in this specific list, the concept is important to understand. If you're ready for a challenge but don't have space for larger models, RG is a fantastic choice. The extra parts and precise assembly require patience, but the result is a stunning display piece.
- More parts and complex assembly than HG
- High level of detail and articulation
- Ideal for intermediate builders
Master Grade (MG): The Enthusiast's Choice
Master Grade kits are 1/100 scale, making them larger and more detailed. They often include inner frames, moving parts, and a higher level of realism. MG kits are more expensive and take longer to build, but they offer a satisfying and intricate building experience. They are best suited for experienced hobbyists who appreciate fine details and are willing to invest time and money.
A prime example is the RGM-79 GM Ver. 2.0 MG. This kit is part of the Master Grade line and offers a detailed build with a standard edition. It's a great choice for collectors who want a classic mobile suit with a high level of detail. The larger scale also makes it a centerpiece for any display.
- Larger scale (1/100) with more presence
- Complex assembly with inner frames
- Higher price, but worth it for the detail
Other Grades and Special Editions
Beyond the main grades, there are also Super Deformed (SD) kits, which are chibi-style and highly collectible, and specialty sets like the SDWH - Sergeant Verde Buster DX Set. These are fun, quick builds that add variety to your collection. Additionally, accessory sets like the Gunpla Battle Arm Arms HG allow you to customize and enhance your existing kits with extra articulation and weapon options.
When choosing a kit, consider not only the grade but also the specific mobile suit design and any special features. Some kits come with additional weapons or effects parts, which can add value. Always check the product details to see what's included.
- SD kits offer a cute, stylized look
- Accessory sets can enhance your builds
- Special editions may include exclusive parts
Decision Rules for Choosing a Grade
- If you're a beginner: Start with an HG kit like the MS-05B Zaku I HG. It's simple, affordable, and will teach you the basics without frustration. You'll complete your first build quickly and gain confidence.
- If you want more detail but have limited space: Choose an RG kit. It offers intricate detail in a 1/144 scale, so it doesn't take up much room. You'll enjoy a challenging build that results in a highly detailed model.
- If you're an experienced builder or want a display piece: Go for an MG kit like the RGM-79 GM Ver. 2.0 MG. The larger scale and complex assembly are worth the extra time and cost. You'll have a stunning model that showcases your skills.
