# How to Make a Diorama for Scale Models: Planning, Base, Scenery and Display Source: https://modelbuildlab.com/blog/how-to-make-a-diorama-for-models Published: 2026-10-31 Publisher: Model Build Lab A diorama is a small scene built around a model, such as a tank in a muddy field, a car outside a garage or a ship at a dock. To make one, plan the story and scale, build a sturdy base, shape the terrain, paint and texture it, add details like grass and props, and place the model last. Starting with a simple scene on a small base is the easiest way to learn, and you can add complexity as your skills grow. ## Start with a simple idea The best first diorama has one clear story: a vehicle stuck in mud, a plane parked on a grass strip, a figure standing in front of a wall. A single focal point keeps the scene readable and stops a first project from becoming overwhelming. Sketch the layout on paper, think about where the model will sit and decide where the viewer's eye should go. Choose the scale before you buy anything, because every element has to match it: the model, figures, buildings, trees and ground detail. A 1/35 military diorama needs 1/35 figures and accessories, while a 1/72 aircraft scene uses much smaller parts. Mixed scales are easy to spot and make a scene feel off, even if people cannot say why. ## Choose a base and frame A diorama base can be wood, thick foam board, a picture frame or a ready-made plinth. It should be flat, rigid and slightly larger than the footprint of the scene. Wood and thick board resist warping when you add wet materials like glue and paint, while thin cardboard can bend as it dries. Seal a wooden base or paint it before you start to keep moisture from warping it. Then think about the edges. A framed edge, either from molding or a simple wooden border, gives the finished piece a clean look and a place to add a label. Keep the size manageable so it fits your shelf or display case.

Foam is lightweight and easy to shape with a hobby knife, but cut it carefully and work on a cutting mat. For a scene with a road or pavement, texture sheets or modeling compounds can create cobbles, asphalt or dirt tracks. Cover the foam with a textured layer, such as modeling paste, spackle or a thin layer of plaster, to hide seams and give the ground surface. Press tools, stones or tires into the surface while it is wet to leave marks and tracks. Allow it to dry fully before painting, since trapped moisture can cause cracks or smell, and follow the material maker's instructions.

Earth tones like browns, tans and grays work for most outdoor scenes. Dry brushing is a quick way to add depth without fine detail, and it makes a flat surface look natural. Then add ground cover: fine sand, small stones, static grass, flock and tufts. Brush on scenic glue or a diluted white glue mix and sprinkle the material over it, then tap off the excess. Layer different textures, such as bare dirt in the middle and grass at the edges, because real ground is rarely uniform. Our guide to diorama spray adhesive and scenic glue compares products for this step. Work from the back of the scene toward the front, and from large shapes to small ones. Large areas of ground cover go on first, then rocks, then plants, then the smallest debris. Doing it in that order keeps glue from marring the finished parts, and it is easier to add a small item last than to remove one that ended up in the wrong place.

Place props so they look as though they were used, not arranged. Odd numbers and uneven spacing feel more natural than neat rows, and a few items overlapping the model help it blend into the scene. Trees, bushes and grass tufts add height and color. You can buy them or make them from natural materials such as dried plants, wire and foam, though real plants should be dried and sealed. For water, use a product made for model water and follow its instructions, since some resins and gels need ventilation and careful pouring.

Then test its position on the dry base and mark where it will go. A few small dots of glue or putty under wheels, tracks or feet keep it from shifting. Add mud, dust or splashes to the lower parts of the model so it blends with the ground rather than sitting on top of it. Take a step back and look at the scene from different angles. Does the model look anchored in the setting? Do colors work together? A little shadow-like darkening around the contact points can make a big difference. Make final adjustments, then leave everything undisturbed to dry thoroughly. ## Protect and display it Dust is the enemy of any diorama, and fine scenery collects it quickly. A clear display case or box keeps the scene clean and protects delicate parts from knocks. Keep the finished piece away from direct sunlight, which can fade paint and weaken some adhesives, and from damp areas. If you handle the diorama, hold it by the base, not the model or fragile scenery. For travel, secure the model and use padding. As you finish each project, note what worked and what you would change, because every diorama teaches something for the next one. ## Frequently asked questions Can I make a diorama with no experience? Yes. A small base with one model and a simple patch of ground is a good first project, and each scene teaches you something for the next. What is the best material for terrain? Foam covered with a textured compound is popular because it is light, easy to carve and takes paint well. Check each product's instructions before use. How big should the base be? Slightly larger than the scene, with enough room around the model to frame it. A smaller base finishes faster and fits more easily in a case. Do I need an airbrush? No. Brushes, dry brushing and spray cans are enough for most dioramas, and many scenes use almost no airbrush work at all. ## Related buying guides - https://modelbuildlab.com/best/best-diorama-supplies - https://modelbuildlab.com/best/best-diorama-spray-adhesive-scenic-glue - https://modelbuildlab.com/best/best-display-cases-models - https://modelbuildlab.com/best/best-cutting-mats-models
