对我来说不是太大也不是太小用英语怎么说

"Just right" 是一种常用说法，表示某事物对某人来说刚好合适，不是太大也不是太小。这个说法来源于童话故事《金猪》中的一句话："This porridge is too hot! This porridge is too cold. Ah, this porridge is just right!"（这碗粥太烫了！这碗粥太凉了。啊，这碗粥正好合适！）

举个例子：

The temperature in the room is just right. (房间里的温度正好合适。)
The amount of sugar in this drink is just right. (这杯饮料里的糖刚好。)
The size of this shirt is just right for me. (这件衬衫的尺码对我来说正好合适。)
