Mockup best practices
Match Instagram's exact dimensions
Use the correct aspect ratio for your post type. Square is 1:1 (1080x1080), portrait is 4:5 (1080x1350), and Story is 9:16 (1080x1920). Wrong ratios get cropped.
Keep captions realistic
Instagram truncates captions after 2-3 lines in the feed. Write your first 125 characters carefully — that's what followers see before "more."
Use real engagement data
For case studies, use actual engagement numbers from your posts. For pitches, use projected metrics based on your average performance.
Add profile context
Upload the brand's actual profile picture and username. This makes the mockup feel authentic and helps clients visualize the real post.
Export at 2x for presentations
Always export at 2x resolution for crisp images in presentations and on retina displays. Low-res mockups look unprofessional.
Create multiple variations
Generate 2-3 mockup variations per concept. Show clients different caption options, image crops, or engagement scenarios to choose from.
