Meta this week announced that Instagram for TV is testing a dedicated home for horizontal video on television screens - a feature that acknowledges, directly, that the vertical 9:16 format at the core of Instagram Reels was never designed for the largest screen in the home.

The format mismatch that has always been there

Instagram built its video identity around the vertical Reel. A 9:16 ratio filling a phone screen held upright, swiped with a thumb, consumed in a personal and portable context. That format has been enormously successful on mobile. According to Instagram, Reels receive 3.5 billion daily shares across the platform. But a phone is not a television, and a television is not a phone.

When Instagram for TV launched on Amazon Fire TV on December 16, 2025, the core of the product was Reels organized into interest-based channels. The content was vertical. Playing it on a widescreen television means black bars fill the horizontal space, the resolution was composed for a small handheld display, and the navigation paradigm - designed for a touch screen - does not exist in the living room. These are known problems. Platforms have faced them before. What Meta is testing today is one answer.

According to Instagram's announcement dated June 22, 2026, the platform is testing a dedicated home for horizontal videos on Instagram for TV. Meta says it heard from viewers who wanted this - a separate space for the landscape format native to traditional television rather than the vertical orientation of Reels. The feature is in testing, not fully deployed. But its existence signals something worth examining: Meta is acknowledging that vertical video and television are not natural partners, and that a distinct pathway for horizontal content is needed if Instagram is going to function as more than a phone-oriented service displayed on a big screen.

What horizontal video actually changes for creators

For creators, the distinction is production-level. A vertical Reel is shot on a phone held upright. The frame is composed for portrait viewing, with the subject centered in a narrow column of space. A horizontal video uses the 16:9 widescreen frame that cinematography has used for decades, that broadcast television uses, and that every television screen is physically shaped to display. The two formats require different cameras, or at minimum different intentional choices about how to hold and compose a shot.

Until today's announcement, Instagram's television app had no meaningful place for horizontal content. A creator who shot in 16:9 landscape - standard for YouTube, for film, for broadcast - would see that content appear letterboxed or misrepresented on Instagram's mobile surface, and absent from Instagram for TV entirely. The horizontal video test changes that. According to Instagram, the feature gives creators more ways to reach audiences and makes it easier to enjoy content designed for the TV screen. The phrasing is deliberate: "content designed for the TV screen." It recognizes that some content is already produced for television - it just had no pathway into Instagram's living-room product until now.

This opens a new surface for a category of creators who have historically found Instagram's vertical-first architecture limiting. Filmmakers, documentary producers, travel videographers shooting wide landscapes, sports creators accustomed to the 16:9 broadcast frame - these are groups whose existing content library suddenly becomes potentially compatible with Instagram for TV in a way it was not before. The question is whether Instagram can build discovery and recommendation infrastructure around horizontal content, or whether the vertical Reels feed remains the dominant logic of the platform.

The competitive context: how YouTube handled the same problem

YouTube faced a version of this problem from the opposite direction. Its core content has always been horizontal 16:9 video. When YouTube Shorts launched and succeeded, the platform had to accommodate vertical 9:16 content within an ecosystem built for landscape viewing. YouTube Shorts is now watched for 2 billion hours every month on television screens, a figure Kurt Wilms, YouTube's Senior Director of Product Management for TV, described in a June 5, 2026 Creator Insider podcast as "an insane number." But YouTube's path to that number involved solving the format mismatch rather than ignoring it. On the TV home screen, YouTube presents Shorts in horizontal rows by content category, with a dedicated player experience that puts vertical video inside a widescreen display environment using controlled black bars. The navigation switched from swipe to remote-button. The lean-back viewing dynamic replaced the active scrolling behavior of a phone.

Meta is now working through an analogous transition, but in the opposite direction. Instagram is built on vertical. Television is horizontal. The horizontal video test is Meta's equivalent of YouTube building a dedicated remote-control Shorts experience - an acknowledgment that the format and the screen have to be reconciled deliberately, not assumed to be compatible.

The VAB and TVision "Impression Gap" report from February 2026 found that premium video sessions on CTV averaged 1 hour and 18 minutes, compared to YouTube's 52-minute average. Session length on television reflects how people actually watch in a living room. They lean back, they stay, they share the experience with others in the room. A vertical phone video running on a television screen with black bars filling a third of the display is not the same experience as content composed for the 16:9 frame. The format is part of the attention signal.

The advertising implications of aspect ratio

For the marketing community, the horizontal video test raises a question that is practical and structural. Meta's aspect ratio requirements already span 25 ad placements across its platforms, and the complexity of managing 9:16, 1:1, 4:5, and 16:9 creative across different surfaces is a documented operational burden for advertising teams. Adding a dedicated horizontal surface on Instagram for TV would add one more format to that matrix - but this time, a format that aligns with rather than conflicts with existing broadcast and streaming television creative standards.

Advertisers buying connected television today typically produce creative in 16:9. That is the standard for programmatic CTV, for streaming pre-roll, for OTT inventory. If Instagram for TV eventually develops an advertising product - which Meta has not announced - and if that product includes horizontal placements, then advertisers could potentially deploy existing television creative on the Instagram surface without reformatting. That would be a structural difference from how Meta's social video advertising has historically worked, where the 9:16 vertical requirement has meant dedicated social production for every campaign.

The co-viewing dynamic amplifies this. Google Ads updated its reporting on June 2, 2026 to count all viewers present in front of a connected TV screen when an ad plays, not only the account holder. An ad on a television is watched differently than an ad on a phone: it is often watched by multiple people simultaneously, in a shared context, without a thumb hovering over the skip button. Horizontal video designed for that environment fits the medium. Vertical video adapted for it does not, at least not without a display compromise.

Research by Media.net published in November 2025 found that 90% of consumers expressed interest in seeing vertical video on publisher sites - but that the same data showed connected TVs representing only 2% of short-form vertical video consumption. Smartphones dominated at 81%. The data suggests that while vertical video has successfully migrated across web surfaces, the television screen remains resistant to the format. Horizontal video on Instagram for TV is an attempt to work with that resistance rather than against it.

Vertical versus horizontal: what the platform decisions reveal

The vertical format's dominance on social platforms is not accidental. It emerged from the phone held in a hand, from the architecture of TikTok, Instagram, and Snapchat, from the physical orientation of a pocket device. It also reflects a creative economy: the easiest video to make on a phone is vertical, and the billion-scale creator ecosystems on these platforms have built their output around that ease.

But the television screen has not changed shape. It is still 16:9, still horizontal, still designed for widescreen content. YouTube's Q1 2026 TV update bringing AI search and family controls to smart TVs is one signal of how seriously the platform treats the living-room screen as a distinct product environment. YouTube's connected TV investment spans navigation, resolution, audio quality, and discovery - and its content has always been primarily horizontal. Instagram is starting from the other side of that format divide.

The horizontal video test does not resolve the tension - it opens a pathway. Meta is not replacing vertical Reels on the TV app. According to Instagram's announcement, horizontal video is getting a "dedicated home" - a separate space within the product, not a replacement for the existing vertical feed. That framing is careful. It suggests Meta is not committing to horizontal as the television standard, but is acknowledging that the current vertical-only approach leaves a gap.

AdPlayer.Pro scaled to 551 million daily ad requests while extending vertical video support across its outstream formats in May 2026, a signal of how much investment has flowed into vertical as a web-wide format. The same report noted that a Media.net study found 90% of consumers wanting vertical video on publisher sites. But publisher sites are not television screens, and the economics of the living room are different. Longer sessions, shared viewing, widescreen hardware, and higher CPM inventory expectations create a different context for content and advertising than the scrolling mobile feed.

What creators should understand about this test

The horizontal video test matters for creators in a specific way: it changes the production calculus for making content that reaches television audiences through Instagram. Until today, the rational choice for a creator optimizing for Instagram was to shoot vertically, always. The platform's recommendation systems, its visual interface, its aspect ratio architecture all pointed in that direction. Meta expanded Instagram Reels to up to three minutes in length in January 2025 - but those longer Reels remained vertical.

A dedicated horizontal surface on Instagram for TV introduces a different incentive. Creators who already produce content in 16:9 - whether for YouTube, for brand deals that require broadcast specs, or for documentary and film projects - now have a potential pathway into Instagram's television audience without reformatting their work. That is a new audience surface that did not exist six months ago.

The feature is in testing and its discovery mechanics are not yet described. Instagram has not detailed how horizontal content will be surfaced to television viewers, whether it will be recommended algorithmically, or how the dedicated home for horizontal video integrates with the interest-based channels already being tested. These questions matter because a format that exists but cannot be discovered is not commercially meaningful for creators.

What is clear is the directional intent. Instagram for TV, as of June 22, 2026, supports Samsung Smart TVs from 2020 models and newer, joining Amazon Fire TV (since December 16, 2025) and Google TV (since February 24, 2026). According to Meta, those three ecosystems together cover the majority of connected TV devices in the US. The horizontal video test runs across a platform that now has meaningful hardware reach. The format question is not hypothetical - it is being tested at scale, on devices already in American living rooms.

The bigger picture for programmatic buyers

For media buyers and programmatic advertisers, the horizontal video development is a pre-commercial signal. Instagram for TV does not have advertising products. Meta has not announced ad formats, auction mechanics, targeting parameters, or brand safety frameworks for the television surface. What exists today is a content product with a format structure that is beginning to align with how television advertising works technically.

CTV advertising budgets have expanded significantly, with programmatic CTV contribution ex-TAC at Magnite reaching $82.3 million in Q1 2026, up 30% year-over-year, with CTV crossing 51% of the company's total net revenue metric for the first time. That growth is happening on platforms that serve 16:9 content. If Instagram for TV eventually joins that ecosystem with horizontal ad placements, the creative compatibility question - whether existing CTV creative can run on Instagram without reformatting - becomes a practical buying consideration.

Samsung Ads opened Smart TV home screens to programmatic buying via The Trade Desk and Google DV360 on June 10, 2026, powered by Magnite SpringServe. Instagram for TV is now available on Samsung Smart TVs as of today. The two developments are not formally connected, but they share hardware. A connected TV advertising infrastructure that supports programmatic buying and a content platform that is beginning to support horizontal video are operating on the same screens. The distance between those two facts is where the advertising opportunity eventually forms.

Timeline

Summary

Who: Meta, through its Instagram platform, testing horizontal video as a dedicated feature within Instagram for TV. Creators who produce content in 16:9 landscape format are the primary group affected by this change. Advertisers watching the connected TV market are the secondary audience for its implications.

What: Instagram for TV today began testing a dedicated home for horizontal 16:9 video on television screens - a format distinct from the vertical 9:16 Reels that have defined Instagram's video identity on mobile. The test acknowledges a fundamental mismatch between Instagram's default format and the physical shape of television screens, and opens a new surface for creators who produce widescreen content.

When: The horizontal video test was announced on June 22, 2026, as part of a broader set of Instagram for TV features being tested. Instagram for TV itself launched on Amazon Fire TV on December 16, 2025.

Where: The horizontal video feature is being tested within Instagram for TV, now available across Amazon Fire TV, Google TV, and Samsung Smart TVs in the US. Samsung coverage extends to 2020 models and newer.

Why: Meta says it heard from viewers who wanted a dedicated home for horizontal content. The deeper reason is structural: vertical video composed for a phone screen does not translate cleanly to a widescreen television display. A dedicated horizontal surface gives creators a pathway to reach TV audiences with 16:9 content and brings Instagram's format architecture closer to the standards that television advertising and broadcast production already use.
