Quick answer: Product Hunt asks for two visual assets at different sizes: a small square thumbnail in the feed and a wide gallery image on the product page. Getting the thumbnail right matters more than it looks, because it is the only visual the hunter sees before clicking.

The specs

Asset Size Notes
Thumbnail 240 × 240 px Square; shown in the feed and the daily list
Gallery images 1270 × 760 px Wide 5:3; the first image is the hero
Thumbnail file Under 3 MB PNG or JPG
Gallery file Up to the platform limit PNG or JPG; 2+ images recommended
Video The platform's accepted formats Optional; embeds on the listing

These specs are current as of late 2026; verify on the launch form before submitting, since the upload requirements change occasionally.

The thumbnail

The 240×240 thumbnail is read at a small size:

  • The logo or one word, large.
  • A simple, high-contrast background.
  • No small text; it is unreadable at the feed size.
  • The brand color fills the square, not a busy screenshot.

The thumbnail and the X image are not interchangeable; the feed crop is square.

The first gallery image is the hero on the listing:

  • The product in the moment of the core job.
  • The annotated screenshot with the key steps.
  • A real workflow, not a blank landing page.
  • Two or more gallery images are recommended; most of the day's leaders include several.

The video

A short demo video is a strong addition, and the listings that include one are common among the top products. The 20–40 second walkthrough covers the job end to end; the launch video guide covers the production.

The full asset set

The Product Hunt images are one part of the launch asset checklist, which also covers the maker comment, the gallery, and the social set.

How the assets are produced

The workflow most small teams use is: take the real product screenshots, frame them in the 1270×760 canvas, and generate the square thumbnail and the matching social set from the same brand system. A tool like Neatico generates the correctly sized gallery, thumbnail, and social images together from one product description, so the feed and the listing stay visually consistent.

Common mistakes

  • A screenshot shrunk into the 240×240 square; the UI is unreadable.
  • Small text in the thumbnail.
  • The gallery image with no margin, cropped at the edges.
  • The logo lost on a busy background.
  • Uploading only one image where the gallery expects more.

Frequently asked questions

Can I use the same image for X and the thumbnail? No; X is 1200×675 and the thumbnail is square, so the crop differs. Is the thumbnail the logo? Usually the logo or a single strong mark works best at 240×240. How many gallery images? At least two; the strongest listings use four to six. Does the video replace the images? No; the video supplements the gallery, and the thumbnail is still required.

Design the thumbnail for the small square first, then fill the wide gallery with the real workflow. The click is won in the feed.
