I built my first board game insert out of foamcore in 2019, and it looked great for about six months. By the end of 2026, the foam was dented, the glue lines were yellowing, and the lid no longer closed cleanly. That experience pushed me to test laminated chipboard for my next five projects, and the difference was immediate. This guide will walk you through how to decide between a foamcore or laminated chipboard insert so you don’t repeat my early mistakes.
Whether you’re organizing one new game or your entire collection, the material you choose affects setup time, durability, and how much you’ll enjoy the build itself. I’ll show you where each option wins, where it fails, and how to make a confident decision before you start cutting.

What Is Foamcore (and Why Hobbyists Love It)?
Foamcore is a lightweight material made of a polystyrene foam core sandwiched between two layers of paper. Standard 5mm foam board is the thickness most board game insert builders use, and you can find it at any craft or office supply store.
The reason foamcore took over the DIY board game insert community is simple: it’s forgiving. You can score and snap it with a sharp utility knife, mistakes can be patched with extra glue, and a single $5 sheet can prototype half a box. Our team has built inserts with foam board for games like Wingspan, Terraforming Mars, and Gloomhaven, and the speed-to-cost ratio is hard to beat for one-off projects.
What Is Laminated Chipboard?
Laminated chipboard is dense pressed paperboard (the same family as the back of a cereal box, only much denser) coated with a printed or solid-color laminate on one or both sides. It is the same material used for trading card game playmats, book covers, and commercial board game inserts like those from Gamegenic.
Regular chipboard has been used in DIY inserts for years, but the laminated variety adds a smooth, sealed surface that resists moisture, hides the brown interior, and holds crisp edges much longer than foam. Many hobbyists who switched from foam core to laminated chipboard reported the same thing I did: the inserts look professional out of the box and stay that way.
Foamcore vs Laminated Chipboard Insert: The Direct Comparison
When you put foamcore and laminated chipboard side by side, the differences fall into five categories: cost, time, durability, weight, and skill required. None of these alone decides the winner, but together they tell you which material fits your project.
Cost: A 20×30 inch sheet of 5mm foamcore runs $3 to $6 at most stores. Laminated chipboard costs roughly $1.50 to $3 per square foot, and a typical insert uses 4 to 8 square feet. Expect to spend $6 to $24 on chipboard versus $5 to $15 on foam for the same box.
Time: A foamcore insert for a medium-weight game takes 4 to 8 hours to design, cut, and glue. The same insert in laminated chipboard takes 6 to 12 hours because each cut needs to be clean and final; there is no scoring-and-snapping shortcut.
Durability: Foamcore wins on initial shock absorption but loses badly over time. The foam crushes under repeated pressure, dents from any heavy components, and the paper faces tear along stress lines. Laminated chipboard holds its shape for years, even with heavy miniatures.
Weight: Foamcore inserts add almost no weight to the box. Laminated chipboard can double or triple the empty box weight, which matters if you store your collection upright on shelves.
Skill required: Foamcore tolerates mistakes and rough cuts. Laminated chipboard punishes sloppy work, so you’ll want a fresh blade, a precise straightedge, and patience.
Pros and Cons of Each Material
Here’s the short version of what I tell anyone who asks me which to pick.
Foamcore pros: cheap, widely available, fast to cut, easy to glue, accepts repair work, and perfect for prototypes.
Foamcore cons: degrades within 1 to 3 years under heavy use, dulls blades fast, the foam core crumbles at cut edges, and the white paper faces scuff and stain easily.
Laminated chipboard pros: professional appearance, holds shape for years, supports heavy components, sealed surface resists moisture, and the laminate hides the rough interior.
Laminated chipboard cons: higher material cost, slower build, requires sharper blades, mistakes cannot be undone without starting over, and the inserts are noticeably heavier.
One forum user summed it up well: “I don’t use foamcore anymore as I found the inserts weren’t aging well. I now use black chipboard, which holds up a lot better.” That matches my own testing across seven inserts over two years.
Tools and Materials You Need
The good news is the basic toolkit is the same for both materials. The differences are in quality and a couple of extras.
Tools you need for foamcore:
Snap-off utility knife (a fresh blade matters more than the brand)
Self-healing cutting mat (A2 size minimum)
Metal straightedge or square ruler
White PVA craft glue
Flathead pins or weights to hold pieces while drying
Pencil and measuring tape
Tools you need for laminated chipboard:
Snap-off utility knife with extra blades (chipboard dulls blades in 2 to 3 cuts)
Self-healing cutting mat
Metal straightedge or square ruler
Contact cement or hot glue (PVA bonds poorly to laminate surfaces)
Clamps or heavy weights
Optional: a box cutter with replaceable heavy-duty blades
If you already own the foamcore toolkit, you only need to budget for extra blades and a different adhesive to switch materials.
How to Decide Between a Foamcore or Laminated Chipboard Insert?
Now the core question: how do you pick the right material for your project? I use a four-step framework whenever a friend asks, and it works whether you’re building for one game or fifty.
Step 1: Look at the game itself. Heavy miniatures, metal coins, or thick card decks point to laminated chipboard. Light cards, cardboard tokens, and wooden cubes do fine in foamcore. If the box is already heavy, extra foam weight won’t matter; if the game is light, chipboard can make the box feel premium.
Step 2: Consider how often you’ll set it up. A weekly game night demands durability. A once-a-year family game can live happily in foamcore. The harder you use the insert, the faster foamcore breaks down.
Step 3: Check your budget and time. If you have a tight timeline or a limited budget, foamcore wins. If you have a weekend to spare and want a finished piece that lasts a decade, laminated chipboard is worth the investment.
Step 4: Think about your storage. Upright shelf storage puts constant pressure on inserts. If you store games vertically, laminated chipboard resists compression far better. Foamcore dents and warps under sustained weight.
Choose foamcore if: you’re prototyping a design, you need it done this weekend, the game has light components, or you want to test a layout before committing to a permanent build.
Choose laminated chipboard if: the game is heavy, you play it often, you want it to look polished on the shelf, or you’re building an insert you’ll keep for the next 10 years.
Consider a combination: Many hobbyists use laminated chipboard for the base trays and heavy-component wells, then add thin foamcore dividers on top. This gives you the durability where it matters and the flexibility where it helps. I’ve used this approach for three games now and it’s the best of both worlds.
Common Mistakes to Avoid
Whether you pick foamcore or laminated chipboard, beginners run into the same handful of problems. Skip the frustration by watching for these.
Dull blades. A worn blade crushes foam and tears chipboard laminate. Swap blades every 3 to 5 long cuts, no matter how sharp they feel.
Wrong adhesive. PVA glue is fine for foamcore paper faces but won’t bond well to the laminate coating on chipboard. Use contact cement or hot glue for laminated chipboard.
Ignoring lid clearance. Measure the inside of the box at multiple points. Many box lids curve inward, and a tray that fits the bottom may not fit the top.
Not measuring twice. Chipboard mistakes are expensive to redo. Foamcore forgives a bad cut; chipboard does not.
Forgetting expansion space. If you’re inserting tokens and components that come in plastic bags, leave room for the bag thickness, not just the loose components.
Frequently Asked Questions
What are the disadvantages of using foamcore?
Foamcore degrades within 1 to 3 years under heavy use, dulls utility knife blades quickly, crumbles at cut edges, scuffs easily on the paper faces, and the foam core crushes under heavy components. Gluing can also be messy because PVA soaks into the paper layer.
What is stronger than foam core board?
Laminated chipboard is stronger than foam core board for board game inserts. It holds shape under sustained pressure, resists dents from heavy components, and the sealed laminate surface protects against moisture and tearing. Plywood and MDF are even stronger but harder to cut at home.
What do I need to build a foamcore board game insert?
You need a snap-off utility knife with fresh blades, a self-healing cutting mat, a metal straightedge or square ruler, white PVA craft glue, flathead pins or weights to hold pieces while drying, a pencil, and a measuring tape. 5mm foam board sheets are the standard thickness for board game inserts.
Is a DIY foamcore insert better than a 3D printed or store-bought one?
DIY foamcore inserts are cheaper and customizable but less durable than 3D printed or store-bought options. 3D printed inserts offer precise tolerances and last for years. Store-bought inserts are designed by the publisher to fit perfectly. DIY inserts make sense when no commercial option exists or when you want a custom layout.
Should I use black or white foam board?
Both work, but black foam board hides scuffs and stains better over time, especially inside an insert that will be handled often. White foam board shows every smudge but is easier to find and usually cheaper. For inserts that will be visible on the shelf, black is the better long-term choice.
How do I keep pieces from shifting when I store the box upright?
Use snug compartments sized to the component dimensions, add a foamcore lid or tray cover on top of the components, and leave enough vertical clearance that the box lid presses gently on the top layer. Some builders also glue a thin felt or foam pad to the bottom of each compartment for a friction fit.
Final Verdict
The choice between a foamcore or laminated chipboard insert comes down to how you plan to use the game. Foamcore is the right answer for prototypes, light components, tight timelines, and tight budgets. Laminated chipboard is the right answer for heavy components, frequent play, upright storage, and inserts you want to keep for a decade.
If you’re deciding on your very first insert, start with foamcore to learn the techniques. Once you’ve built two or three, you’ll know whether the extra time and cost of laminated chipboard is worth it for the games you love most. And if you can’t choose, the combination approach gives you laminated chipboard bases with foamcore dividers, and that’s exactly what I’d recommend for your next big box of miniatures.
