Why is 300x300 listed in two groups?

Because the same dimensions are needed in two worlds: as an image asset in Google Ads and as a product tile in an email template. The file is the same, the design rules differ, since in email the text belongs on the image.

How many tiles fit across an email row?

At the usual 600 pixel body width, two tiles side by side with a gutter. Most templates stack them on phones, so check that a single tile still reads well at full width.

Which file format and file size?

myfeedr delivers 300×300 as PNG (lossless) and JPG. For trafficking, the JPG is what counts: around 50 KB is a realistic target for this size – small enough for any network without visible quality loss.

What does the format cost?
