new to 3ds, quick question

how do you tell what the download size is of something on the shop before downloading it? i can't seem to find it. on my ps3 and ps4, the download size is at the top of that downloads page but i don't see it anywhere on the 3ds

It tells you on the information page, right before you download, how many blocks you have, and how many you will have after the download.

ok thanks. nintendo has a weird way of doing the smallest things
