Quick answer: A social media kit is the set of images, captions, and profile assets prepared for the launch, so the post can go out on each platform at the right size and with the right text. It is the launch-specific counterpart of the evergreen brand kit.

What is in the kit

The images

  • The feed images for X, LinkedIn, Facebook, Instagram, and the other platforms.
  • The Story and the Reels frames in 9:16.
  • The square image in 1:1.
  • The vertical image for the 4:5 and 3:4 feeds.
  • The OG image for the link shares.
  • The Product Hunt gallery and the thumbnail.

The captions

  • The caption for each platform, adjusted to the character limit.
  • The hook and the CTA.
  • The hashtags and the handles, where they belong.
  • The X thread or the carousel if the message is longer.

The profile assets

  • The temporary profile banner or the pinned post.
  • The avatar, if the launch is the major event.
  • The bio link and the UTM-tagged URL.

The source text

The product description, the key screenshots, and the launch blog post are the inputs; the product launch kit is the broader bundle.

Why the kit is separate

Each platform crops and displays differently:

  • X: 1200×675; the single image is 16:9.
  • Instagram: 1080×1080, 1080×1350, and 1080×1920 for the Story.
  • LinkedIn: 1200×627.
  • Facebook: 1200×630.
  • RedNote: 1080×1440.
  • Pinterest: 1000×1500.

The full table is in the social media size guide. The one image uploaded everywhere gets cropped differently on each platform.

How to build the kit

  1. Write the product description and the value proposition.
  2. Prepare the screenshots and the hero.
  3. Design the base images at the source size.
  4. Export the platform-specific ratios.
  5. Write the caption for each platform.
  6. Place the assets in the one folder with the clear names.
  7. Schedule the posts; the content calendar and the scheduling guide cover the rollout.

The annotated structure

A small launch kit commonly contains:

  • Five to eight feed images.
  • Three Story frames.
  • The OG image.
  • The captions for four platforms.
  • The thread and the carousel if needed.

The one announcement to a week of posts plan maps the kit to the schedule.

The localization

The kit is rebuilt for each market: the text is translated, the captions are rewritten, and the images are re-rendered in the target language; the multilingual guide covers it.

Building the kit with AI

The manual work is resizing the same message into the nine ratios and rewriting the caption for each platform. The AI generation makes the kit consistent when the source is the one product description; Neatico is built around this exact kit, generating the images and the captions for the platforms together so the text and the brand stay aligned.

The review

The kit is checked before it goes:

  • The image sizes and the safe zones.
  • The caption lengths and the handles.
  • The claims and the facts; the review pass.
  • The links and the UTM tags.

What to avoid

  • The one image used on every platform.
  • The key text in the cropped edge.
  • The caption copied without the platform adjustment.
  • The assets scattered across the folders on the launch day.
  • The missing OG image for the shared link.

Frequently asked questions

How many images are in the kit? Five to eight feed images plus the Story frames and the OG image is a reasonable small launch set. Is the social kit the same as the brand kit? The brand kit is the evergreen identity; the social kit is the launch set built on it. Does the kit include the video? The launch video and the clips are often included. Can one kit cover every language? The layout is shared; the text and the captions are localized per market.

Build the kit once, export every platform ratio, and write the captions in the same sitting. The launch day is for posting, not for resizing.
