Exact Character limit for few variable types

As per documentation, for 254 characters or less, the string field is a single-line text field. Anything 255 characters or above appears as a multi-line text box.

Please note that this is expected behavior.

By default, multi-line text fields have a 4,000-character limit. To help users see how many characters remain before they reach the limit, you can enable the glide.ui.textarea.character_counter property."

I don't think any limit for Multi Line Text but it can be 4000

For wide single line text you can set the max length validation using onChange client script
