How to use Social Media Post Mockup
Create realistic social media post mockups for Instagram, Twitter/X, Facebook, LinkedIn, and TikTok — without a design tool or real account. Enter post text, upload a photo or choose a placeholder, and select a profile picture and username. Download the mockup as a PNG for presentations, portfolio pieces, client proposals, ad concepts, or content calendar screenshots.
- Select the platform for the mockup: Instagram feed post, Twitter/X post, LinkedIn post, etc.
- Enter the account name and handle (can be fictional for mockup purposes).
- Upload a profile picture or select an avatar placeholder.
- Enter the post text with hashtags, mentions, and emojis as needed.
- Upload a post image or leave blank for a text-only post.
- Adjust the like/comment/share counts for realism, then download as PNG.

Use cases for post mockups
Social media mockups are used across many professional contexts. Marketing agencies create mockups to present client content strategies without needing to publish test posts. Freelancers include mockups in portfolios to show social media management work without screenshots of real accounts. Product teams use mockups to spec how a brand will look on social before a launch. Educators and course creators use them as teaching examples. Journalists use mockups to illustrate social media dynamics in news articles without risking copyright issues with real screenshots. Influencers use mockups to pitch collaboration concepts to brands.
Design guidelines for realistic mockups
For maximum realism, match the platform's current UI: font sizes, spacing, icon placement, and color scheme. Instagram posts use a 1:1 or 4:5 ratio for the image area with the caption below. Twitter/X shows the full handle (@username) and display name separately. LinkedIn posts show connection degree (1st, 2nd, 3rd) next to the name. Facebook posts show the privacy selector (Public globe icon) next to the timestamp. Most platforms now display a light and dark mode variant — create both if the mockup is for a formal presentation. Use system fonts (San Francisco for iOS elements, Roboto for Android/Material).

| Instagram feed (portrait) | 4:5 | 1080×1350 px | 8 MB |
| Instagram Stories | 9:16 | 1080×1920 px | 4 GB (video) |
| Twitter/X post image | 16:9 | 1600×900 px | 5 MB |
| LinkedIn post image | 1.91:1 | 1200×628 px | 10 MB |
| Facebook post image | 1.91:1 | 1200×630 px | 10 MB |
| TikTok video | 9:16 | 1080×1920 px | 287 MB |
| Pinterest pin | 2:3 | 1000×1500 px | 32 MB |
