Instagram Image Sizes Explained

Instagram supports three main image formats: square posts at 1080×1080 pixels (1:1 aspect ratio), portrait posts at 1080×1350 pixels (4:5), and Stories/Reels at 1080×1920 pixels (9:16 full-screen vertical). Using the wrong dimensions means Instagram will crop your image unpredictably, often cutting off important content.

This resizer generates all three Instagram sizes from a single upload, plus 10 additional sizes for Facebook, Twitter/X, LinkedIn, YouTube, TikTok, Pinterest, and WhatsApp. Smart crop mode center-crops to fill each aspect ratio. Fit mode preserves your entire image with an elegant blurred background fill. Download individually or as a ZIP file — all processing happens in your browser with zero uploads.

For best results, start with an image at least 2000×2000 pixels. The higher the source resolution, the sharper every generated size will look. JPEG output with 90% quality is the sweet spot for Instagram — it balances file size with visual quality perfectly.
