FAQ
- Why make thumbnails at a 1:1 ratio?
- Because most feed and search listings crop to a square. Naver Blog's neighbor feed, Naver mobile search results, and the Tistory mobile home screen all render thumbnail cards as 1:1 squares — and so do plenty of other platforms. Designing at 1:1 from the start means your text lands inside the crop instead of getting sliced off at the edges.
- Can I reuse the same finished thumbnail on both Tistory and Naver Blog?
- Yes — both platforms support the same 1000x1000px square format, so one exported file works for either. Naver does sometimes re-resize the featured image automatically though, so it's worth checking the preview after uploading to make sure no text got cropped in the process.
