Scale guide
1:400 vs 1:450 scale: which one suits your collection?
Scale describes the reduction from the real aircraft, not its quality. A 1:400 model is slightly larger than a 1:450 model; the right choice depends on your display space, favourite aircraft and collecting plan.
In brief
- 1:400 is about 12.5% longer than 1:450 for the same aircraft.
- 1:450 fits more aircraft into a compact cabinet.
- Both scales can work together when they are grouped deliberately.
What the numbers mean
At 1:400, one centimetre represents four metres of the real aircraft. At 1:450 it represents 4.5 metres. Divide the real dimensions in centimetres by 400 or 450 to estimate the model.
An Airbus A380 measuring about 72.7 metres is roughly 18.2 cm long in 1:400 and 16.2 cm in 1:450. Its wingspan is close to 20 cm or 17.7 cm, so shelf depth matters as much as width.
Detail, presence and cabinet space
1:400 has more visual presence and a little more surface for doors, windows and logos. Print quality, mould accuracy and assembly still matter more than a few millimetres.
1:450 makes large fleets easier to display. The difference is most noticeable on wide-body aircraft such as the A380 and B747.
- ✓Choose 1:400 for impact and a selective collection.
- ✓Choose 1:450 when space is limited or you want more airlines.
- ✓Leave clearance around wings and stands.
Can you mix both scales?
Yes. Group by scale, use separate shelf levels, or reserve 1:400 for centrepieces and 1:450 for a wider fleet. The difference becomes obvious mainly when two versions of the same aircraft sit side by side.
For strict size comparisons, photography or airport dioramas, use one scale. For a collection built around liveries, registrations or memories, do not reject a meaningful model solely because of scale.
A three-step decision
Measure the usable width, depth and height of your cabinet. Estimate how many aircraft you plan to add this year. Finally, check the scale of models you already own. Those three answers usually make the decision clear.
Frequently asked questions
Which is larger, 1:400 or 1:450?
1:400. The same aircraft is about 12.5% larger in length and wingspan.
Which scale has more detail?
1:400 provides slightly more room, but mould and print quality have a greater effect.
Can both scales share one cabinet?
Yes. Grouping by airline, aircraft family or shelf level makes the difference feel intentional.
