HG, RG or MG Gundam kits: what’s the difference?
HG, RG and MG are Bandai Gunpla model-kit lines with different approaches to size and detail. High Grade (HG) is a useful starting point for a straightforward build, Real Grade (RG) puts intricate detail into a compact 1/144-scale model, and Master Grade (MG) offers a larger 1/100-scale project. Choose the experience and display size you want, then check the specific kit: the grade alone does not tell you everything about its construction.
HG, RG and MG at a glance
Gunpla means Gundam plastic models. Bandai’s introductory Gunpla guide explains the hobby, while its model-line overview describes the different approaches behind HG, RG and MG.
| Line | Typical scale | Why consider it? |
|---|---|---|
| HG — High Grade | 1/144 | A broad choice of mobile suits and an approachable place to learn assembly. |
| RG — Real Grade | 1/144 | Detailed mechanical construction in a compact format. |
| MG — Master Grade | 1/100 | A larger display model with an emphasis on internal construction and articulation. |
Read the scale printed on the specific box. A scale such as 1/144 is a ratio, not a fixed height: different mobile suits can produce differently sized models at the same scale. For the same subject, 1/100 is larger than 1/144.
What does 1/144 versus 1/100 look like?
For the same subject, a 1/100-scale model is 1.44 times as tall as a 1/144-scale model. As an example, an 18-metre subject works out to 12.5 cm (4.92 in) at 1/144, or 18 cm (7.09 in) at 1/100. This is scale arithmetic, not a guaranteed finished height for every kit.
Grade and scale tell you different things: HG and RG can have the same scale while offering different construction and detail. Check the exact kit dimensions if it needs to fit a particular shelf.
Start with HG if you want to learn the basics
For a first build, an HG of a mobile suit you actually like is a sensible shortlist. It gives you a chance to practise reading the instructions, identifying parts and cleaning up attachment points before choosing a more involved project.
HG does not mean “no articulation.” For example, Bandai’s 2015 HGUC 1/144 RX-78-2 Gundam has double-jointed elbows and knees. Bandai also distinguishes it from the earlier 2001 HGUC release. That is a good reason to check the exact version instead of shopping by character name alone.
Choose RG for detail without moving to 1/100 scale
RG suits a builder interested in how a compact model fits together. Allow yourself time to handle small components and follow the sequence carefully; a smaller model is not automatically a simpler project.
Engineering also changes within the RG line. Bandai describes a newly designed internal frame for the RG 1/144 RX-78-2 Gundam Ver.2.0. You can see this edition on our RG RX-78-2 Gundam Ver.2.0 product page. Toy Snowman’s original RG RX-78-2 Gundam listing is a different edition. Do not assume that advice or photographs for Ver.2.0 describe the original kit.
Choose MG when a larger model is part of the appeal
MG is worth considering if you want a 1/100-scale display and enjoy assembling internal mechanisms. For example, Bandai’s MG 1/100 RX-78-2 Gundam Ver.2.0 includes an articulated inner frame and a Core Fighter that converts into a Core Block.
You can compare that identity with Toy Snowman’s MG RX-78-2 Gundam Ver.2.0 product page. These are examples of specific editions, not a promise of availability. Check each product page for current stock or preorder status.
Before choosing a kit
- Pick a subject you want to display. You do not need to work through every grade in order.
- Check the full name and version. Match the grade, scale and edition across the box, listing and instructions.
- Check included accessories. Confirm the weapons, decals and display stand rather than assuming every photographed item is included.
- Plan your workspace. Use good lighting, a clear work surface and a container for small parts.
- Read the current listing. Confirm availability and whether the item is an in-stock purchase or preorder.
Three useful follow-up questions
Do I need glue or paint?
Bandai’s introductory guide explains modern Gunpla’s snap-fit assembly and moulded colours. Glue and paint are generally unnecessary for a basic build; follow the instructions for your exact kit. Painting is an optional finishing choice.
Which tools should I prepare?
For the HGUC example in Bandai’s guide, cutting pliers are part of the preparation and tweezers help with small decals. Check your kit’s instructions for the required tools; do not assume every Gunpla has tool-free parts.
Can I look at the instructions before buying?
Bandai provides an online manual page for the 2015 HGUC RX-78-2 and a searchable manual catalogue. Coverage is incomplete, so a missing online manual does not establish anything about a kit’s authenticity or difficulty.
