Portrait feed posts still reward 1080×1350 real estate, so micro-stories and customer quotes fit comfortably without feeling like stretched banners. Use the Social post preset here to jump straight into that aspect ratio, then tighten line spacing if your copy is short or loosen it when you are sharing a short paragraph from a blog recap.
Instagram compression prefers smooth gradients and medium-weight fonts; extremely thin strokes can shimmer after upload. If you notice moiré on photographic backgrounds, switch back to a solid brand color for the session, or export PNG and let Instagram transcode once rather than re-saving JPEGs repeatedly. Always pair the graphic with a caption that repeats the quote verbatim for screen readers and search.
After export, you may still need platform-specific crops for Stories or Reels covers— run the asset through SmartFlexa's Resize Image helper. The shared Text to image generator documents the same controls under the canonical tools URL.
