Aircraft model scales compared: 1:500, 1:400, 1:200 and 1:144

You’re standing in a model shop or scrolling through an online catalog, and next to every plane there’s a number: 1:500, 1:400, 1:200, sometimes 1:144. In the photo all the models look the same size; on the shelf they’re worlds apart. An A380 in 1:500 is barely longer than a ballpoint pen, while in 1:144 it takes up half a meter of table. This guide explains aircraft model scales side by side: how big the models really get, what detail each scale can show, where to find which makers and how to settle on the right scale for your collection.

What a scale actually tells you

A scale is a ratio: the first number stands for the model, the second for the original. 1:500 means every distance on the real aircraft is divided by 500 – length, wingspan, height, every window and every landing gear leg. The bigger the second number, the smaller the model.

A simple conversion helps in practice: how much model do you get per meter of original?

With these values you can convert any aircraft in your head. Take the length from the profile, such as the roughly 37.6 meters of the Airbus A320, multiply it by the value from the tile, and you have the model length in millimeters. In 1:500 that’s about 75 millimeters, in 1:200 about 188.

A second effect matters, and many people underestimate it: length and width grow at the same time. A 1:400 model is only a quarter longer than the same aircraft in 1:500, but it takes up a good half more area on the shelf. Going from 1:500 to 1:200, the model becomes two and a half times as long and needs more than six times as much floor space.

Where the odd numbers come from

The fact that 1:144 and 1:72 in particular are so common has to do with the Anglo-American system of measurement. In 1:72, one inch on the model stands for six feet on the original, in 1:144 for twelve feet. These values come from the world of plastic kits and have stuck around there. The round scales 1:200, 1:400 and 1:500, on the other hand, are typical of prefabricated metal collector models, so-called die-cast models.

How big the models really get

The following table converts well-known types into the four main scales. It is based on the length and wingspan from our aircraft type profiles; the values are rounded to the millimeter and given as length times wingspan. Individual makers deviate slightly in execution, for example through stands or simplified wingtips.

Aircraft type	1:500	1:400	1:200	1:144
ATR 72-600	5.4 × 5.4 cm	6.8 × 6.8 cm	13.6 × 13.5 cm	18.9 × 18.8 cm
Airbus A320neo	7.5 × 7.2 cm	9.4 × 9.0 cm	18.8 × 17.9 cm	26.1 × 24.9 cm
Boeing 737-800	7.9 × 7.2 cm	9.9 × 9.0 cm	19.8 × 17.9 cm	27.4 × 24.9 cm
Airbus A350-900	13.4 × 13.0 cm	16.7 × 16.2 cm	33.4 × 32.4 cm	46.4 × 45.0 cm
Boeing 747-400	14.1 × 12.9 cm	17.7 × 16.1 cm	35.3 × 32.2 cm	49.0 × 44.7 cm
Boeing 777-300ER	14.8 × 13.0 cm	18.5 × 16.2 cm	37.0 × 32.4 cm	51.3 × 45.0 cm
Boeing 747-8	15.3 × 13.7 cm	19.1 × 17.1 cm	38.2 × 34.2 cm	53.0 × 47.5 cm
Airbus A380	14.5 × 16.0 cm	18.2 × 20.0 cm	36.4 × 39.9 cm	50.5 × 55.4 cm

Two things stand out. First, widebodies are about twice as long as narrowbodies in every scale – if you mostly collect long-haul, you need noticeably more space per model. Second, the A380 is the only aircraft on the list that is wider than it is long. For it, shelf depth decides, not shelf width. How to tell the two giants apart in real life is covered in the guide How to tell an A380 from a Boeing 747.

1:500 – the whole fleet in one display case

1:500 is the smallest of the common collector scales for airliners. A narrowbody fits on the palm of your hand, a jumbo on a postcard. The scale is especially popular in Europe. The maker Herpa from Franconia shaped it with its Herpa Wings brand: the company introduced its first 1:500 model in 1987, back then still made of plastic. Today the models are largely made of metal. You can read more about the brand and its collector scene at Collecting Herpa Wings.

What 1:500 does well:

• Lots of airlines, types and special liveries in little space.
• Regional aircraft such as the ATR or the Embraer E190 stay tiny, but stand next to long-haul jets at the correct scale.
• Ideal if you want to recreate a fleet history – for example, all the types of one airline over decades.

Where 1:500 hits its limits:

• Fine details such as antennas, pitot tubes or door outlines are often only hinted at or printed on.
• Landing gear is inevitably delicate and fragile when handled.
• Registrations and titles are legible, but very small.

For spotters who like to collect airlines or work through a long type list, 1:500 is the obvious scale: the collection can grow broad without taking over the living room.

1:400 – the compromise with more substance

1:400 is about a quarter larger than 1:500 and is especially common among die-cast brands outside Europe. Gemini Jets, for example, offers its range in 1:400 and 1:200, and many other brands serve this scale too. Herpa offers 1:400 only to a very small extent – so if you collect in Europe, you often end up with other makers. You’ll find an overview of the most important brands in the article Makers of display models.

The increase in size sounds small, but you notice it. Engines look more voluminous, landing gear sturdier, windows and livery details clearer. An A320 measures about nine centimeters, a jumbo just under 18 – that still fits well on common shelves and in display cases.

For many collectors, 1:400 is the scale that feels “right”: you pick up the model and recognize the type immediately, without it turning into a decorative object that needs a table of its own.

1:200 – the single piece for your desk

In 1:200, a widebody becomes roughly 33 to 38 centimeters long. This is the scale where you can really see doors, maintenance panels, antennas and livery details. Many makers offer finished metal models here, Herpa and Gemini Jets as well as other brands. There are also simple plastic snap-fit models without landing gear, which often serve as promotional or travel agency models. Airlines frequently hand out such models as giveaways or sell them in their own shop; more on this in the article on airline and airport shops.

The price for this impact is space. A single jumbo in 1:200 takes up as much area as a good six jumbos in 1:500. Building a complete fleet in 1:200 is therefore the exception. Many collectors use the scale deliberately for favorites: the plane from their first own flight, a special livery or the type that got them into spotting.

1:144 – the modeler’s scale

For airliners, 1:144 is mainly a kit scale. Here you usually don’t buy a finished model, but plastic parts, decals and building instructions. The appeal lies in doing it yourself: you decide on the livery, weathering, registration and level of detail. Many kit makers offer well-known airliners in this scale, and specialized decal suppliers provide airline liveries to go with them.

A jumbo gets almost half a meter long in 1:144, and an A380 has a wingspan of over 55 centimeters. As a collecting scale for whole fleets that’s impractical, but as a building project it’s ideal: the parts are big enough to work cleanly, and small enough that the finished model still fits on a sideboard. How to tackle your first kit is explained in the guide Building aircraft kits.

And the other scales?

Besides the four main scales, there are a number of other sizes you’ll run into:

• 1:72 is the classic scale for military aircraft and smaller propeller planes. An airliner would be huge in it.
• 1:250 and 1:100 show up mostly with simple plastic snap-fit models.
• 1:600 and 1:1000 are niche scales with a small range.
• 1:160 only turns up occasionally, for example with historic propeller aircraft.

For an airliner collection these scales usually play only a supporting role. Pick one of the big four, and you’ll find the widest selection in the long run.

Level of detail compared

Size isn’t everything – the question is what you actually see in which scale. The table sums up the typical differences. It describes tendencies; individual makers and models can turn out better or plainer.

Criterion	1:500	1:400	1:200	1:144 (kit)
Typical construction	Finished model, mostly metal	Finished model, mostly metal	Finished metal model or snap-fit model	Plastic kit you build yourself
Landing gear	very delicate	recognizable, fragile	detailed, partly with movable parts depending on the model	depends on the kit and the effort you put in
Antennas and probes	often simplified or left out	partly present	mostly present	as parts or scratch-built
Registration	legible, but tiny	easy to read	very easy to read	freely selectable via decal
Space per widebody	about postcard size	about A5 sheet area	about A3 sheet area and more	roughly half a meter in every direction
Collector breadth	very high	high	rather selected single pieces	project by project

How many models fit on your shelf?

For most collectors, space is the most important factor. When you line models up side by side, wingspan is what counts, because the wings lie across the shelf edge. The calculator shows you how many models of one type fit in a row.

An example: in an 80-centimeter-wide shelf compartment, about nine narrowbodies fit side by side in 1:500, but only four in 1:200. With widebodies in 1:200 it’s just two. Staggered or angled placement, overlapping-wing arrangements and wall mounts get more out of it – the article Storing and displaying aircraft models collects ideas for this.

Which scale fits you?

In the end, the choice depends less on technology than on how you collect. The following questions help sort it out.

Scale and spotting: a collection with a connection

For plane spotters, a model collection has a special appeal: it can become a three-dimensional companion to your sighting log. Some people deliberately buy models with exactly the registration they photographed themselves. Others build a collection along their type list or focus on special liveries, because those are the highlights out at the fence too.

This is where scale comes into play again. In the small collector scales, special liveries and rare airlines tend to appear in a bigger selection than in 1:200. So if you want to find as many registrations from your own spotting life as possible on your shelf, you’ll usually be better served by 1:500 or 1:400. If you instead want to celebrate a single experience – the first A380 at your home airport, say – you go for the big 1:200 model.

If you’re just wondering whether models are your thing at all, start with the introduction Collecting aircraft models. And if you want to give a model as a gift: ask about the scale of the existing collection first. You’ll find a few more ideas in the gift ideas for plane spotters.

Conclusion

The four big scales cover four ways of collecting. 1:500 delivers the greatest breadth in the smallest space, 1:400 adds noticeable detail without blowing the budget of space, 1:200 is the scale for large single pieces and 1:144 belongs mainly to the modelers. Before you buy, quickly work out how big your favorite type will get, measure your shelf and then consciously choose a main scale. That saves you from bad purchases and makes sure your collection looks on the shelf just as coherent as the real planes on the apron.
