What matters
Snapchat Story dimensions at a glance
Snapchat stories fill the entire phone screen at 1080×1920. The format is optimized for quick, vertical mobile consumption with automatic advancement.
Stories are Snapchat's core content format. Proper sizing ensures your content looks intentional and native, not cropped from a different platform.
Horizontal or square content looks tiny with large blank areas. The auto-zoom fallback often crops important details unpredictably.
