Reddit has four main ad types: image, video, carousel and free-form. Around them sit special formats and tools: Reminder ads and AMA ads for events, Interactive ads, commerce formats, and Max campaigns for automation. Every ad can run in two placements, the feed and conversation pages. The rule that decides most of it: pick the format by what you want people to do. Specs checked against Reddit's Ad Unit Specifications in October 2026.


What are the main Reddit ad types?

Ad type

What it is

Best for

Image

One image, a headline and a link

Your first tests and simple messages

Video

One video with a headline and a link; autoplays in the feed

Showing a product or a game in action

Carousel

2 to 6 swipeable cards, each with its own link and caption

Several products or steps

Free-form

A post-style ad with up to 20 images, 5 videos and 40,000 characters of text

Stories, deep dives and launches


Image ads

The simplest format and an easy place to start. The headline can be up to 300 characters, though Reddit recommends 100 or fewer and calls 80 the safer limit. Images can be JPG, PNG or GIF up to 3 MB. Sizes are in our Reddit ad specs, sizes and types.


Video ads

One video with a headline, MP4 or MOV, up to 1 GB, 2 seconds to 15 minutes. Videos autoplay in the feed on desktop and mobile. Full specs in our Reddit video ad specs.


Carousel ads

Up to 6 images or GIFs, each with its own destination link and a caption of up to 50 characters, so you can send people to a different page per card. Use the same aspect ratio on every card.


Free-form ads

Free-form ads look like a normal Reddit post, with rich text, inline links, images and video. Reddit said its early tests in 2024 showed free-form ads beating all other ad types on average click-through rate by 28%. Your results will vary, so test it. Free-form ads don't get an automatic thumbnail, so upload one.

The 4 main Reddit ad types

What special Reddit ad formats exist?

  • Reminder ads: image or video ads with a "Remind Me" button. Reddit opened them to all advertisers on 13 April 2026. People who tap it get notified before and when your event goes live. Good for launches, drops and sales.

  • AMA ads (beta): promote a scheduled AMA with RSVP and reminders.

  • Interactive ads: quizzes, countdowns, trivia and custom games built on Reddit's Developer Platform. Reddit said it would roll them out to managed advertisers in 2026, so ask your Reddit rep about access.

  • Redditor Highlights: real, positive Reddit posts about your brand added to image and video ads. Generally available since June 2026.

  • Commerce formats: Collection ads and a Shopify product ads integration arrived in March 2026, and Shopping listing ads, which show products from several brands, were in alpha in June 2026.

  • Max campaigns: not a creative format but a campaign type where Reddit automates budget, bids and creative mixes. See Reddit Max campaigns in 2026.

Special Reddit ad formats

What are the two Reddit ad placements?

Placements decide where your ad shows, not what it looks like. Both work with every ad type.

  • Feed: the Home, Popular and community feeds.

  • Conversation: the page where people read a post and its comments.

In our experience, feed is the safer choice for cold audiences, because conversation placements bring cheap clicks that are often accidental. See The most common Reddit ads mistakes.


Which Reddit ad type should you use?

  • Testing a first message: image ads

  • Showing a product or game in action: video ads

  • Selling several products or explaining steps: carousel ads

  • Telling a story, going deep or launching something: free-form ads

  • Promoting a date, like a launch or sale: Reminder ads or AMA ads

  • Scaling a setup you've already proven: Max campaigns

Whichever you pick, test more than one. In our eBook, we start with 4 to 6 ads in a single ad group and pause the weakest after 7 to 14 days.
