A brilliant sculpt can look strangely out of place the moment it joins the rest of your force. Perhaps its head is larger than every helmet in the unit, its rifle reaches halfway across the base, or a supposedly human-sized hero towers over a vehicle hatch. This miniature scale compatibility guide is for avoiding that moment before primer, paint and assembly turn a promising addition into an expensive shelf piece.

Scale is not a single, universal number in tabletop gaming. It is a mix of nominal height, body proportions, base footprint, posing and the visual language of a particular range. A miniature can be technically close in scale yet still clash badly beside another. The goal is not always mathematical perfection. It is a collection that looks deliberate on the table and behaves properly in the game you play.

Start with the game, not the catalogue label

The first question is simple: what must this miniature do? A display figure has very different requirements from a tournament army character, an RPG villain or a scenic civilian placed behind a bar counter.

For models used in a ruleset, start with the game’s official expectations. Many systems specify base sizes, line-of-sight conventions, unit footprints or model heights. If a replacement or proxy needs to move through dense terrain, fit into unit coherency, or represent a specific profile, those practical limits matter more than whether the sculpt is marketed as 28 mm or 32 mm.

For role-playing games, the base grid usually matters most. A creature intended to occupy a 1-inch square should generally sit on a base that fits that space, even if its cloak, wings or weapon overhang a little. For large monsters, check both the base and the reach of the pose. An impressive dragon is less useful if its tail sweeps across three other player spaces every time it is moved.

Casual games allow more freedom, but a quick conversation with your gaming group is still wise. Most players welcome a well-chosen alternative miniature. Problems tend to arise when one model is so oversized or underbased that it gains a meaningful gameplay advantage.

What miniature scale numbers actually mean

A stated scale is usually a useful starting point, not a guarantee. Traditional 28 mm often refers loosely to the height of an average human figure from foot to eye level. A 32 mm range follows the same idea at a larger size. The complication is that not every sculptor measures the same way, and not every manufacturer uses the term consistently.

A 28 mm realistic-proportion human might be slim, with a smaller head, narrower hands and a believable weapon length. Put it next to a 28 mm heroic-scale warrior and it can look child-sized. Heroic scale exaggerates key features so a model reads clearly from across a gaming table: heads, hands, fists, boots and weapons become larger, while limbs may become sturdier.

This is why a ruler cannot settle every compatibility question. Two infantry miniatures can both measure 32 mm to eye level but feel entirely different because one is built like a realistic special-forces operator and the other like a power-armoured demigod.

Nominal scale versus true scale

True scale attempts to preserve human proportions as size changes. Nominal scale is the label used to group models, often with some tolerance for style. Most tabletop collections contain a degree of nominal-scale mixing already, particularly where characters are meant to look imposing.

As a practical rule, a difference of roughly 2 to 3 mm in human-sized figures is often manageable when the models share similar proportions and basing. Beyond that, compatibility depends heavily on the role. A larger champion can look commanding. A line infantryman who is a head taller than every squadmate will usually look accidental.

Poses can mislead you

Measure or compare from the soles of the feet to the eye line where possible. A crouching sniper, lunging knight or leaping alien may appear shorter in product imagery despite being designed for the same scale as a standing figure. Conversely, a miniature standing on tactical rubble may be taller than its companions even before it reaches its base.

When comparing photos, look for reference points: helmets, shoulder pads, pistols, doors, crates and standard base rims. A studio photograph without a comparison model can make scale judgement difficult, especially with oversized weapons and dramatic forced perspective.

The miniature scale compatibility guide to bases

Scale determines whether models look right together. Bases determine whether they work on the table. Treat these as related but separate decisions.

If your game assigns a specific base size to a unit, match that base unless your group has agreed otherwise. Base diameter affects movement, engagement distances, objective control, formation spacing and how easily a model can occupy terrain. Swapping a 25 mm base for a 32 mm one may make a model look more balanced, but it can change the model’s game footprint considerably.

Height matters as well. A tall scenic base can improve the presence of a character, but it can also alter line of sight in systems where model height is relevant. Keep standard troops on consistent base thickness and reserve raised cork, rock and ruins for leaders, monsters and display-focused pieces.

For conversions, begin with the required base and build upwards. Dry-fit the legs, torso, arms and equipment before committing to a dramatic rock or ruined wall. This prevents the common problem of a striking pose that cannot stand securely, fit in a transport tray or reach around nearby unit members.

There are four compatibility checks worth making before you assemble:

• Diameter: Does the base match the unit, game profile or encounter grid?
• Height: Will scenic material make the model unusually tall for gameplay?
• Overhang: Can weapons, capes and tails pass through terrain and sit beside other models?
• Balance: Is the model stable enough for regular transport and play?

Terrain must agree with your miniatures

Terrain compatibility is one of the fastest ways to make a table feel immersive or make it feel like a collection of unrelated kits. Doors, ladders, windows, barricades and walkways all reveal scale immediately.

For 28-32 mm heroic science-fiction miniatures, a doorway needs enough clearance for broad shoulder armour, backpacks and upright weapons. A realistically scaled building may be accurate in architectural terms but awkward for chunky infantry to enter. Slightly oversized terrain is often the better gaming choice because it leaves room for movement, fingers and models carrying large guns.

Fantasy terrain benefits from the same thinking. Tavern furniture, dungeon doors and market stalls should accommodate both ordinary adventurers and larger armoured characters. If your party includes hulking barbarians, mounted heroes or a wide range of creature sizes, favour open interiors and removable roofs over tightly scaled rooms.

Smaller-scale games require another mindset. At 10 mm or 15 mm, visual mass matters more than fine detail. A building that looks perfect beside individual infantry may disappear once whole formations, vehicles and woods crowd the table. Keep roads, ruins and area terrain proportionate to the way armies manoeuvre, not only to a single model photographed close-up.

Mixing brands without breaking the illusion

Independent ranges are one of the great pleasures of the hobby. They offer stranger aliens, more characterful adventurers, elaborate conversion pieces and faction concepts that mainstream ranges rarely touch. Mixing them successfully is less about brand loyalty and more about controlling visual cues.

First, match the scale family. A 32 mm heroic infantry range will generally blend more comfortably with another chunky 32 mm range than with slender 28 mm true-scale figures. Then match the genre language. Riveted industrial armour, clean high-tech panels, gothic iconography and organic biomechanical detail can coexist, but they need a reason within your army or setting.

Paint and basing do a great deal of the work. A shared rim colour, ground texture, weathering approach and limited palette can make differently sculpted miniatures read as one force. The same is true for RPG collections: repeat stone colour, dungeon grime or woodland foliage across the party and their enemies to create visual continuity.

Conversion bits deserve an extra dry-fit stage. Shoulder pads, heads, weapons and bionics are often sized around a particular body style. A part may attach cleanly yet look comically large, or require a small spacer, green stuff collar or careful trimming to sit naturally. Resin is forgiving for experienced hobbyists, but careful test fitting saves more time than repairing a glued joint later.

When deliberate mismatch works

Not every mismatch is a mistake. Scale contrast can tell a story. An ancient war construct should feel larger than ordinary infantry. A tiny goblin scout, towering mech, swollen plague creature or colossal demon benefits from visual separation. The key is repetition and intention.

Use size differences consistently. If one alien species is taller and longer-limbed than humans, keep that relationship across the force. If every officer has a slightly more heroic build than the rank and file, it reads as stylisation. One random oversized soldier in an otherwise uniform squad reads as a purchasing error.

Before buying a full unit, test one miniature if you can. Place it beside the models, terrain and bases it will actually share. Check it at arm’s length, not only under a hobby lamp. That is the distance at which your opponents will see the force, and it is where a coherent army, warband or adventuring party earns its presence.

A compatible collection does not need every figure to be identical in height or sculpting style. It needs clear choices: the right footprint, a believable shared scale language and enough room for the stories you want to put on the table.
