iOS Mail Text Wrapping Issue

I’ve been having a problem in iOS mail for several weeks/months. The window that it gives me to type my email in is not wide enough — Or the text is not wrapping properly. I don’t have the issue on the mac, but it is present on both my iPad and iPhone. For even a two line email, I have to scroll sideways to read what I have written. The text is too wide for the screen. Can anyone think of a fix? It’s extremely annoying and I have resorted to composing emails in drafts and pasting it into mail, which is also extra steps that should be unnecessary.
