@Robin_Pike,
Welcome to the Airtable Community!
As far as I can tell it is not possible to position fields side by side in an Airtable form. :frowning:
If you get good with the Airtable formula editor, you might consider creating a single NameEntered field where somebody could type something like “Mary Smith” and you can parse the names out into first name and last name fields. But covering all the options with names can be a little tricky.
Your other question was, can you make the field boxes less wide? You didn’t paste a screen shot so I’m not sure whether you’re asking about Airtable’s Form view, or about the expanded record view (what you see when you click the little ‘expand record’ button at the far left end of each row). Either way, the basic answer is, you don’t have any control over the width of those boxes. Yes, can be a little annoying when you know that the field is only ever going to contain one word…
