A shelf full of Gundam kits can look like a wall of acronyms: HG, RG, MG, PG, SD, FM. A good Gunpla grades comparison turns that alphabet soup into a shopping shortcut. Grades generally tell you a kit’s scale, engineering complexity, parts count, detail level, and intended building experience - but they do not simply rank from worst to best.
WELCOME TO UTOPIA, where the right kit is the one that matches your time, budget, favorite mobile suit, and display goals. Whether you want a fast build for a weekend or a centerpiece that takes over your workbench, each grade has a lane.
Gunpla Grades Comparison at a Glance
| Grade | Typical Scale | Best For | What to Expect |
| --- | --- | --- | --- |
| Entry Grade | Usually 1/144 | First-time builders | Very simple construction, low parts count |
| High Grade (HG) | 1/144 | New and returning builders | Affordable, broad character selection, solid detail |
| Real Grade (RG) | 1/144 | Builders who enjoy fine detail | Small parts, layered armor, advanced engineering |
| Master Grade (MG) | 1/100 | Dedicated hobby builders | Larger size, inner frames, display presence |
| Full Mechanics (FM) | Usually 1/100 | Big, detailed builds without MG complexity | Strong outer detail and satisfying scale |
| Perfect Grade (PG) | 1/60 | Experienced builders and collectors | Huge size, extensive mechanics, premium project |
| Super Deformed (SD) | Stylized | Casual builders and character fans | Compact, expressive proportions, quick builds |
A grade is a useful signal, not an absolute promise. A newer High Grade can have sharper color separation than an older Master Grade. An RG may have more surface detail than an MG while still being much smaller. Always look at the specific kit, especially when comparing releases from different eras.
Entry Grade Is the Cleanest Starting Point
Entry Grade kits are designed to remove friction. They typically use touch-gate parts that can often be separated by hand, simplified construction, and color-separated pieces that look good without paint. For someone opening their first Gundam model kit, that means less time worrying about tools and more time seeing a mobile suit take shape.
They are also great palette cleansers for longtime builders. After a complex build full of tiny decals and panel lines, an Entry Grade can be a genuinely fun reset. The trade-off is limited articulation, fewer accessories, and less mechanical depth. You are getting a clean representation of the character, not a miniature engineering project.
High Grade Delivers the Best Value for Most Builders
HG 1/144 is the workhorse of Gunpla. It is affordable, compact, widely available across Gundam series, and varied enough to support almost any collection. Want to build a classic RX-78-2, a witchy mobile suit from The Witch from Mercury, a rugged Zeon design, or an army of grunt suits? HG is usually where you start looking.
Most HG kits can be completed in a few hours to a weekend, depending on your pace and how much finishing work you add. Modern HG releases often feature excellent color separation, smart articulation, and crisp proportions right out of the box. A basic nipper, sanding tools, and a panel-lining marker can take one from good to shelf-ready.
The compromise is that HG kits usually have fewer opening hatches, less elaborate inner construction, and simpler hands than larger grades. Some weapons may need more careful posing, and older HG kits can show their age through stickers or limited movement. None of that makes them bad kits. It just means HG rewards builders who value variety, price, and a growing display over maximum complexity.
Pick HG if your collection is built around fandom
For collectors who shop by series, HG makes it easier to build a complete visual lineup. You can put rival suits, team units, and deep-cut favorites together without needing a display case the size of a starship. If your goal is to represent your favorite Gundam universe rather than spend months on one build, HG is a strong home base.
Real Grade Packs Big Detail Into a Small Scale
RG takes the familiar 1/144 footprint and pushes it hard. These kits aim for a realistic, layered look with intricate color separation, moving armor sections, decals, and mechanical details that feel closer to a larger model. A finished RG can look spectacular beside an HG, especially from a few feet away.
That detail comes with a real trade-off: the parts are tiny. RG is less forgiving if you rush runner cleanup, force a joint, or treat a delicate antenna like a handle. Earlier releases are known for more complex pre-assembled inner-frame sections, while newer RG kits often use newer engineering approaches and can be remarkably sturdy when built carefully.
RG is best for builders who already enjoy HG and want a challenge without moving to a larger scale. Give yourself a clear workspace, good lighting, and patience. This is not the grade to build while half-watching a show and hunting for the next piece under your couch.
Master Grade Makes One Kit the Main Event
MG 1/100 kits are larger, more involved, and made for builders who want to spend meaningful time with a single mobile suit. Many include an inner frame, opening armor panels, cockpit details, stronger hands, and a level of mechanical presence that stands out immediately on a shelf.
The 1/100 scale also makes MG more comfortable for people who find RG parts too small. You still get a detailed build, but the pieces are easier to hold, clean, and pose. That said, MG boxes cost more, take up more storage space, and can demand more attention to assembly order. A backpack, transformation mechanism, or weapon loadout can turn a simple-looking suit into a serious project.
Not every MG is equally complex. Some are approachable first 1/100 builds, while others are famous for dense parts counts or challenging transformations. If you are stepping up from HG, choose an MG of a suit you genuinely love. A favorite character carries you through the longer sessions far better than chasing a grade label.
Full Mechanics Is a Smart 1/100 Alternative
Full Mechanics kits sit in a useful space between HG and MG. They are generally 1/100 scale and can offer dramatic proportions, strong surface detail, and a rewarding amount of build time without always using the full inner-frame approach associated with MG.
For builders who want a large, impressive anime design but do not need every hatch to open, FM can be the sweet spot. These kits often prioritize a sturdy finished look and bold shelf presence. Exact complexity varies by release, so compare the individual kit rather than assuming every Full Mechanics box follows the same formula.
Perfect Grade Is a Build You Plan For
PG 1/60 kits are not just larger Gunpla. They are long-form hobby projects. The scale allows for major mechanical detail, elaborate inner structures, large accessories, and, on many releases, LED lighting options. A completed PG becomes a display centerpiece almost by default.
The cost, build time, and display footprint are substantial. You will want room to organize runners, a protected place to display the finished kit, and enough patience to enjoy the process instead of racing through it. PG is ideal when one specific mobile suit means enough to you that you want the biggest, most involved version of it.
Do not treat PG as a required graduation. Plenty of highly skilled builders collect HG, RG, or MG because those grades fit their space and favorite designs better. The best collection is not the most expensive one. It is the one you keep wanting to look at.
SD and Mega Size Follow Different Rules
SD Gunpla uses exaggerated proportions: oversized heads, compact bodies, and tons of personality. They are excellent for quick builds, desk displays, younger hobbyists, and fans who want a stylized version of a favorite suit. Modern SD lines can include surprisingly clever part separation and articulation, but their charm is the look, not realism.
Mega Size goes in the opposite direction, making large-scale builds that emphasize presence and straightforward construction. They are not necessarily more complex than MG or PG. Think of Mega Size as a statement piece for builders with the shelf space to support it.
Choose Your Grade by the Build You Want Tonight
Start with the experience, then select the grade. If you want a fast, low-stress build, choose Entry Grade or SD. If you want the widest selection and the easiest way to collect by series, HG is hard to beat. If tiny mechanical detail sounds fun rather than frustrating, try RG. For a larger hands-on project, look to MG or Full Mechanics. Save PG for the suit you want to make the star of your collection.
One last collector rule: buy the kit that makes you excited to clip the first piece off the runner. A great Gunpla build is not about proving you picked the highest grade. It is about finding your fandom, building it your way, and giving it a place of honor on the shelf.
