RG vs MG Gunpla: Which Grade Should You Build Next?

RG and MG Gunpla differ in scale, part count, and price. Compare the trade-offs and pick the grade that matches your space, budget, and build time.
Quick answer
Choose RG if you want a compact 1/144 kit with high detail and a lower price, and you are comfortable with small parts. Choose MG if you want a larger 1/100 build with more presence on the shelf and easier handling. If you are new to the hobby, MG is usually the more forgiving first build; if space or budget is tight, RG is the better pick.
Scale and shelf presence
RG kits are 1/144 scale, so a finished figure is roughly 12–13 cm tall. MG kits are 1/100 scale, roughly 18–20 cm tall. That difference matters most when you display: an MG needs more vertical clearance and a wider base, while several RGs can share one shelf. If you already own a crowded Detolf or a narrow desk shelf, RG is the practical choice. If you want a centerpiece that reads clearly from across the room, MG wins.
Part count, build time, and difficulty
MG kits generally have more parts and a longer build, often 4–8 hours for a first-timer. RG kits have fewer parts but many are tiny, especially in the head, hands, and inner frame. The difficulty is different rather than strictly higher or lower: MG is more forgiving because parts are bigger and easier to handle, while RG punishes clumsy tweezers work. If you have large hands or poor lighting, MG is the safer build.
Price and value
RG kits usually cost less than MG kits from the same series, but the gap narrows once you add decals, stands, or paint. A cheap RG can become expensive if you buy a separate action base and a decal sheet. An MG often includes more plastic and sometimes a display stand or effect parts. Compare the total cost, not just the kit price. For a budget build, RG plus a third-party stand is still usually cheaper than MG plus the same accessories.
Detail and customization potential
RG kits are known for dense surface detail and color separation out of the box, so they look busy without extra work. MG kits have larger surfaces, which makes them easier to panel line, paint, and decal. If you plan to add waterslide decals or custom paint, MG gives you more room to work. If you want a detailed look straight from the box, RG delivers that faster. Neither grade is better for every builder; it depends on whether you enjoy the finishing process or just want a quick result.
Trade-offs at a glance
- RG: compact and detailed: 1/144 scale, smaller parts, lower kit price, and dense out-of-box detail. You trade easier handling and shelf presence for a smaller footprint and a lower entry cost. Pick RG if space and budget matter more than build comfort.
- MG: larger and more forgiving: 1/100 scale, bigger parts, longer build, and more room for panel lining and decals. You trade a higher price and more shelf space for easier assembly and stronger display presence. Pick MG if you want a centerpiece and a less fiddly build.
- Accessories change the math: A cheap RG plus a stand and decal sheet can approach the cost of a budget MG. Factor in the extras you actually want before deciding. Compare total cost, not just the kit price.
Products that show the trade-off
- MG RB-79K Ball 08 Team Ver. 1/100: MG RB-79K Ball 08 Team Ver. 1/100 is a Master Grade kit with snap-fit assembly and warning stickers. A low-cost MG example: you get 1/100 scale and MG engineering without paying a flagship price, which makes it a good test kit if you are unsure about the grade.
- Gundam Decal 135 The Witch from Mercury Multiuse 3: Gundam Decal 135 The Witch from Mercury Multiuse 3 is a multiuse decal sheet with markings for The Witch from Mercury kits. Decals add detail to either grade, but they are easier to apply on larger MG surfaces; on RG, plan for smaller pieces and more careful placement.
- Warhammer 40000: Chaos Knights: Ruinator: Warhammer 40000: Chaos Knights: Ruinator is a large plastic war machine that can alternatively be built as a Knight Abominant, Knight Rampager, or Knight Desecrator. If you also build Warhammer, this shows a different kind of large-kit commitment; it is not Gunpla, but it competes for the same shelf space and hobby time as an MG.
Which grade fits you?
Best for
- Builders with limited shelf space or a tight budget
- Modelers who want high detail without painting or extra decals
- Fans of 1/144 scale collections and small dioramas
Not for
- Builders who dislike tiny parts or need larger pieces for easier handling
- Anyone who wants a large centerpiece straight out of the box
- Modelers who plan heavy custom paint and need more surface area to work on
