Airtable doesn’t allow us to set an attachment size limit in Airtable forms. Why? This is so critical while having an attachment field in public forms especially. You just can’t bear any random person uploading GBs of file.

I’m not sure why Airtable doesn’t offer that feature, but it’s a fantastic idea and you should definitely submit it as a feature request on the product ideas form here.

In the meantime, until Airtable offers this feature, your #1 best bet for this is to use Fillout’s advanced forms for Airtable.

Fillout is 100% free, and it offers hundreds of features that Airtable’s native forms don’t offer, including the ability to:

I show how to use a few of the advanced features of Fillout on these 2 Airtable podcast episodes:

This is a real and rather unusual gap in Airtable forms in my opinion.  While Fillout is always an option another good option is to route your form through Zapier or Make instead which will allow you to intercept the submission.  You can check the file size early in your flow and reject or flag it before it settles into your base.  It is more setup but everything is kept within tools you may already be using.

If you already have Airtable automations, you can have a step that checks attachment size when a record is created or sends a notification when something oversized comes through.  It isn’t quite a perfect fix but it catches the problems quickly.

Either way, worth submitting this as a feature request because this is a very basic need that somehow has been overlooked.
