Felipe Pires opened us a question related to the size of the text and integer icons in App Builder and Forms (see LEXI-905).

Reviewing the icon library in Clay I found:
_text_

_text-l_
Not found
_integer_

Checking our SVG repository in GDrive I found:
_text_ and _text-l_

_integer_

and in the Figma library:
_text_

_text-l_

_integer_

I'm a bit lost with this issue, so... correct me if I wrong:
PS. I also have to check with the previous members of Lexicon team. The _number_ icon:
Clay
_number_

Gdrive

Figma

@drakonux not 100% sure when the text icon got smaller, but it was during the 1.x to 2.x update. I can update those.
I'm pretty sure decimal, integer, number, text, textbox were drawn smaller to fit the UI for 7.1 / 7.2.
Also I'm unable to find larger versions of integer and number icons.
Thanks, @pat270 for your time. I'll talk with Felipe because the information I found also reveals the same you said: some of the icons we mentioned were drawn smaller by design as you said.
