Compare High Grade and Real Grade Gundam model kits to find the right fit for your experience and goals, with practical advice on complexity, detail, and cost.

Quick answer

HG (High Grade) kits are the best starting point for beginners due to simpler assembly and lower cost, while RG (Real Grade) kits offer more detail and complexity for builders with some experience. Choose HG if you want a quick, satisfying build; choose RG if you enjoy intricate engineering and are ready for a longer project.

Understanding the Grades

High Grade (HG) is the most common Gundam model kit grade, typically at 1/144 scale. These kits have fewer parts, simpler construction, and are very forgiving for first-time builders. They still look great out of the box and are perfect for learning basic techniques like nub removal and panel lining.

Real Grade (RG) also uses 1/144 scale but packs in far more detail, including a pre-assembled inner frame, more color separation, and often small parts that require careful handling. RG kits are designed to look like miniaturized versions of the mobile suits from the anime, but the assembly is significantly more involved.

Key Differences at a Glance

The most obvious difference is part count. A typical HG kit has 100–200 parts, while an RG kit can have 250–400. This directly affects build time: an HG might take 2–4 hours, whereas an RG can take 6–12 hours or more. RG kits also include advanced features like sliding gimmicks and poseable hands, which add to the complexity.

Price is another clear divider. HG kits are very affordable, often under $20, making them low-risk for experimentation. RG kits cost more, typically between $25 and $50, reflecting the extra engineering and detail. If you are unsure about committing to the hobby, starting with an HG is a smart way to test the waters.

Which One Should You Choose?

If you are completely new to model kits, start with an HG. You will get a satisfying result without frustration, and you can always move to RG later. If you have built a few HGs and want a greater challenge, an RG will reward you with a display piece that looks incredibly detailed.

Consider your tools and workspace as well. RG kits often require nippers, a hobby knife, and tweezers for small decals. HG kits are more forgiving with basic tools. Also, RG kits may have very small parts that can be lost easily, so a clean, well-lit work area is important.

Trade-offs at a Glance

Build time: HG: 2–4 hours. RG: 6–12+ hours. HG for a quick project, RG for a weekend build.
Detail and complexity: HG: simpler, fewer parts, less color separation. RG: pre-assembled inner frame, more parts, advanced gimmicks. RG offers a more impressive final look but demands patience.
Cost: HG: typically under $20. RG: $25–$50. HG is lower risk for beginners; RG is an investment in detail.
Skill required: HG: beginner-friendly, forgiving. RG: requires some experience with small parts and careful assembly. Start with HG if you are new; move to RG when you want a challenge.
