The five woods used in model making compared, what balsa really is, the special case of boats, and what to check on a kit before you get started.

The right wood for a model depends on what you're building: balsa for lightweight models like airplanes, basswood for parts you carve and for planking hulls, plywood for sturdy structures and laser-cut kits. MDF and hardwoods like walnut round out the list, one for models you'll paint, the other for finishing. Each wood has its strengths, and above all its limits.

This guide compares them, explains what balsa really is, and covers the case of boats in detail, where several woods sit side by side on the same hull. If you'd rather start from parts already cut from the right wood, our wooden model kits bring together boats, airplanes, and cars to build.

Key takeaways

Balsa, very light, for airplanes and lightweight structures.
Basswood, with its fine grain, for carving parts and planking hulls.
Plywood, sturdy, for structures and laser-cut kits.
A single model often mixes several woods.

What wood should you use to make models?

Five model woods illustrated side by side, balsa, basswood, plywood, MDF, and walnut, with their density, how easy they are to cut, and how they look unpainted — Density, ease of cutting, and unpainted look, on a relative scale from 1 to 5.

Five families of wood cover most of model making. Each has a strength and a limit, and that pairing decides its place in a model.

Balsa is very light and cuts with a craft knife, but it dents at the slightest bump and soaks up glue and paint alike. It's best kept for airplanes, lightweight structures, and architectural models.
Basswood, with its fine, even grain, carves, sands, and bends well. Heavier than balsa, it's used for the first layer of planking on hulls, small carved parts, and strips.
Plywood made of poplar or birch is stable, doesn't split, and laser-cuts very cleanly. Its edge shows the plies and it doesn't carve well: it's the wood for keels, frames, and pre-cut kits.
MDF offers a very smooth, uniform surface, ideal for painting, but it's heavier, doesn't like moisture, and breaks when it's thin.
Hardwoods, walnut and mahogany, have a warm tone and a grain that comes out under varnish. Harder to work, they're used for the second layer of planking, decks, and finishing parts.

In practice, a single model often mixes several woods: a plywood structure, basswood cladding, a few finer finishing parts. Architectural models readily combine balsa, foam board, and MDF. For a miniature house made from scratch, our article on the DIY miniature house details the tools and time you'll need, and our miniature house kits show the result you get with parts already cut.

What is balsa wood?

Balsa is the wood most associated with model making, so much so that it's the classic answer to "model wood, 5 letters" in crosswords. Here's what to know before you buy some.

It's a very light tropical wood that grows in Central and South America; Ecuador is the top producer. It's soft enough to cut with a craft knife and sand in a few passes, which makes it the go-to lightweight wood for model airplanes, where every gram counts. You'll find it in sheets, strips, and blocks, in several thicknesses.

Its flaws come from that softness. It dents under a fingernail, its fibers get crushed by tweezers squeezed too hard, and it soaks up glue and paint alike: you sand it finely and apply a primer before painting. For a part that has to withstand bumps or stay crisp over time, basswood or plywood is a better fit. And if you plan to add color, our guide to painting a wooden model covers the primer and the steps.

Tip: sand balsa finely and apply a primer before painting. Without it, the wood soaks up paint just like glue.

What wood should you use for a model ship?

A boat is the project where the choice of wood matters most, because a traditional hull combines several woods, each in its place. It all depends on the type of kit.

The traditional method: frames, planking, and double planking

In a classic model ship kit, the keel and the frames, the ribs that give the hull its shape, are cut from plywood. They're then covered with a first layer of planking, thin basswood strips laid plank after plank, then often with a second layer in a hardwood, walnut or mahogany, which gives the final color. The masts and yards come from round dowels. In our catalog, The New Port Sailboat 1:70 follows this shipyard method: a hull on ribs, planking laid plank by plank, canvas sails, metal fittings, and a paint finish, for a 41 cm sailboat rated advanced.

Plywood snap-together kits

Laser-cut kits work differently: the plywood parts pop out of the sheets and fit together with tabs and slots, with no planking to lay. The wood stays light and natural, with no painting required. That's the case for most of our boats, like The Flagship, 194 pieces of light plywood for a ship 46 cm long, or The Seahorse Three-Master and its 603 laser-cut pieces. This type of kit lets you build a large sailing ship without the techniques of traditional model making.

To choose your first boat based on piece count and level, our guide to the wooden model ship compares rowboats, sailboats, and three-masters. All our models are gathered among our model ship kits.

Plywood or MDF: how to tell what a kit is made of

When you buy a kit, you no longer choose the wood piece by piece, but its quality is still a good indicator. You can check these points on the product page or when you open the box:

plywood shows thin layers along its edge, while MDF has a uniform edge, like very dense cardboard;
plywood handles thin parts, cutouts, and parts you bend better, while MDF breaks more easily when it's thin;
slightly browned edges are normal: they're the mark of the laser, which cuts the wood by burning it;
a well-fitted tab-and-slot joint almost holds on its own, and glue only makes it permanent.

Our wooden kits come pre-cut with illustrated step-by-step instructions in English. The Biplane, for example, goes together piece by piece in plywood: 105 pieces, one to one and a half hours of building, and a drop of regular wood glue (not included) on the struts to make it sturdy. The Little Display Sailboat, on the other hand, snaps together entirely, with no glue.

What supplies do you need to make a model?

The supplies depend on the wood and the type of model, but a common base covers most projects. If you're starting from raw sheets, plan for a little more:

a precision craft knife with spare blades, a metal ruler, and a cutting mat;
fine sandpaper, or files, to adjust parts and soften edges;
wood glue for wood-to-wood joints, and super glue for small metal parts;
tweezers, and a few clothespins to hold parts while they dry;
for planking, hot water or a plank bender to curve the strips.

Choosing the glue deserves a detour of its own, because each glue has its own setting time and use. Our guide to glue for wooden model kits compares the four main types of glue and how to glue without smudges.

The right wood for your model

For a light airplane or a structure you cut yourself, go with balsa; for carving small parts or planking a hull, basswood; for a sturdy structure, plywood. The best wood for a model is the one that suits the part it has to form, and a well-designed kit makes that choice for you.
