比例这个东西，是根据摆放和把玩时候的方便来决定的。一般我觉得长度和宽度以30厘米左右为上限，再大了拿在手上就像挥大刀，而且过大的金属模型也过于沉重，一不小心失了手，可就香消玉殒了。而过小也不合  适，模型太小，细节完全不能做出，这样就是儿童玩具，不是模型了。

The proportion is determined by the convenience of placing and playing. Generally, I think the maximum length and width is about 30 cm. No matter how big it is, holding it in my hand is like waving a dagger. Moreover, the oversized metal model is too heavy. If I miss it, it will die. And too small is not appropriate, the model is too small, the details can not be made, so it is a children's toy, not a model.

而现在的主力战机模型，以1:72为一个合适的比例，这样F-XX系列和Su-27兄弟都能在30厘米左右。目前1:72主流飞机模型里面。

Now the main fighter model, with a ratio of 1:72, can be about 30 cm for both the F-XX series and the Su-27 brothers. Currently, 1:72 is in the mainstream aircraft model.

1:48：直升机模型一般以1:48为宜（现在市面上的美军直升机模型、共军直升机模型：武直9、武直10都是这个比例，俄军例外，成品里面只能买到塑料的1:72的米-24/28和卡-52）也有少数固定翼战斗机采用这个比例，这样产品细节容易做，但是显得太夯，缺点也容易被放大。

1: 48: the helicopter model is generally 1:48 (currently, the U.S. helicopter model and the Communist helicopter model on the market are all at this ratio, except for the Russian army, which can only buy the plastic 1:72 m-24 / 28 and Ka-52 in the finished products). This ratio is also adopted by a few fixed wing fighters, which makes the details of the product easy to do, but it is too tamping, and the shortcomings are easy to be ignored Big.

1:72：主流战斗机模型比例，书桌摆台刚好合适。

1: 72: the proportion of mainstream fighter model is just right.

1:144：主要做轰炸机模型、运输机模型、预警机模型等（比如Corgi的B-52、E-3）这个我认为是收集大型飞机的佳比例。可以保留一点细节，又不于过大或者过小。

1: 144: we mainly do bomber model, transport model, early warning model, etc. (such as Corgi's B-52, E-3). I think this is the best proportion to collect large aircraft. You can keep a little detail, but not too big or too small.

1:200：这个比例传统上是客机模型。但是近有些厂家，把市面上卖得好的主流战斗机从1:72缩小到这个比例，同样涂装，我没买过，但是好像出货越来越汹涌。

1: 200: this scale is traditionally a model airliner. But recently, some manufacturers have reduced the proportion of mainstream fighters that sell well in the market from 1:72 to this ratio. I haven't bought the same coating, but it seems that the shipment is more and more turbulent.

再小的比例，就缺失太多细节，没意思了。尽管不同厂家，如果同样比例的军事模型，在一起一点也不突兀。这有点工业标准化的意思。

No matter how small the proportion is, there are too many details missing. It's boring. Although different manufacturers, if the same proportion of military models, together is not abrupt. It's a bit of industrial standardization.
