Frequently asked questions
- Is 336x280 worth building next to 300x250?
- Yes, it is quick to derive and unlocks extra inventory. It is a poor standalone choice, though, because plenty of slots cannot take the width. Think of it as an addition rather than a replacement.
- Can I just scale a 300x250 up to 336x280?
- Better not. The aspect ratios differ slightly, so scaling distorts or crops the artwork. Rebuild the layout and spend the extra area on breathing room around the type rather than on a bigger image.
- Which file format and file size?
- myfeedr delivers 336×280 as PNG (lossless) and JPG. For trafficking, the JPG is what counts: around 65 KB is a realistic target for this size – small enough for any network without visible quality loss.
