Introduction: video format as a strategic choice, not an aesthetic one
In audiovisual production and digital communication, video format, meaning the aspect ratio between the width and height of the image, is one of the most decisive technical and strategic variables in how effective content is. It is not merely an aesthetic matter: it is a decision that directly affects distribution, audience engagement, performance on individual channels and, ultimately, the return on the production investment.
The two main formats that anyone producing video content for corporate communications, marketing and social media has to work with are:/
- The horizontal format, with a 16:9 aspect ratio (1920×1080 pixels), derived from the television standard and later adopted by YouTube, projectors, monitors and all desktop screens. It is the format most people instinctively associate with the idea of “professional video”.
- The vertical format, with a 9:16 aspect ratio (1080×1920 pixels), is the direct result of the mobile revolution. Born of users’ habit of holding their smartphone upright, it has become the native standard for TikTok, Instagram Stories, Instagram Reels, YouTube Shorts and Facebook Reels.
Alongside these sits the square format (1:1), a technical compromise between the two, often used for posts on Instagram and LinkedIn.
The choice between these formats cannot be left to chance or habit. It must be the result of precise analysis: where will the video be published? Who will watch it? On which device? With what communication objective? Answering these five questions, the classic 5W framework applied to video strategy, is the starting point for every informed production decision.
Why video format has become a management issue
Until ten years ago, the choice of format was the exclusive preserve of the technical department or the videomaker. Today, with the fragmentation of digital touchpoints and the proliferation of platforms, it has become a decision that belongs to marketing strategy and to the governance of corporate communications.
The data confirm this unequivocally. According to Statista, in 2024 79% of US users watched online video on their smartphones every week Teleprompter, and the trend is growing globally. According to eMarketer’s Global Video Consumption Report, in 2026 mobile devices account for 79.4% of all global video views, with an average of 4.7 hours of daily mobile viewing per adult Amra & Elma. In this landscape, format is not a detail: it is the first filter users apply when deciding whether to keep watching or move on to the next piece of content.
At management level, choosing the wrong format carries a real cost: a horizontal video published in a vertical context such as Instagram Reels will show distracting black bars on either side, losing 40% of the available screen and signalling to the algorithm that the content is not optimised. Data show that users watch up to 90% of vertical videos in mobile ads, but only 14% of horizontal ones Yans Media. Translated into advertising budget, this difference means wasting the vast majority of the investment.

Who uses 16:9 and why
The horizontal format remains the irreplaceable standard for a specific set of communication contexts. It is not a format in decline: it is a format with a specific function, and understanding that function is essential to getting the production right.
16:9 is the ideal format for:
Institutional and corporate content. The corporate presentation video, the company story, the employee onboarding video or the product video for the website homepage: all these formats benefit from the width of 16:9, which allows more elaborate visual compositions and the inclusion of graphics and text elements, and conveys a sense of solidity and narrative completeness.
Productions for events, trade fairs and conferences. When video is projected onto a physical screen, whether the big screen at a corporate event, the monitor on a trade fair stand or the projector in a conference room, the horizontal format is the only technically correct choice.
YouTube content for organic discovery. YouTube remains the world’s second-largest search platform, and its native format is 16:9. Educational content, interviews, in-depth tutorials, brand documentaries and videos aimed at organic search must be produced in horizontal format.
Desktop campaigns and website integration. Any content intended to be viewed mainly on desktop, whether landing pages, display campaigns or videos embedded in the site, must use the horizontal format to ensure optimal rendering.
The compositional advantages of 16:9
From an audiovisual production standpoint, the horizontal format gives directors of photography and directors greater compositional freedom. Its width makes it possible to work with depth of field, to have several subjects interact within the frame, and to include scenic elements that enrich the visual narrative. It is no coincidence that cinema and television have adopted even wider ratios (2.39:1 for CinemaScope) to amplify this effect further.
The vertical format (9:16): the native language of mobile
The rise of vertical: data and context
The vertical format did not emerge from a creative choice by communications professionals: it emerged from user habit. Users hold their smartphones vertically around 94% of the time Teleprompter, and the platforms simply adapted their UX to this behaviour. As a result, 9:16 has today become the “native” format of all mobile-first communication.
Vertical videos on mobile achieve completion rates of around 76%, compared with 54% for horizontal videos Zebracat. A significant gap that translates directly into greater exposure to the message, stronger brand recall and higher conversion rates.
Vertical videos generate 58% more engagement on mobile devices than horizontal ones, and 76% of users say they are more likely to watch a vertical video to the end on social platforms, compared with 49% for horizontal videos Zebracat.
Where and when to choose the vertical format
9:16 is the right choice for:
TikTok, Instagram Reels, YouTube Shorts. These three ecosystems are today the main arena for organic discovery for consumer brands and for anything aimed at reach, virality and acquiring new audiences. The algorithm explicitly rewards content native to the format.
Instagram Stories and Facebook Stories. Ephemeral 24-hour content was born vertical, and vertical it must remain.
Mobile advertising campaigns. Ads on Meta (Facebook and Instagram) and TikTok that use the vertical format perform considerably better. 48% of mobile users remember a brand better after seeing a full-screen vertical ad, compared with 29% after seeing a standard in-feed video Zebracat.
“Human-first” content and authentic storytelling. Vertical has a more personal aesthetic, closer to the language of interpersonal communication. It is the format of the selfie, of UGC, of genuine stories. For brands that want to communicate in an authentic, empathetic and direct way, vertical is the right code.
Reference table: which format for which context
| Context of use | Recommended format | Aspect ratio |
|---|---|---|
| Corporate video | Horizontal | 16:9 |
| Website homepage | Horizontal | 16:9 |
| YouTube (organic content) | Horizontal | 16:9 |
| YouTube Shorts | Vertical | 9:16 |
| Instagram Reels | Vertical | 9:16 |
| Instagram Feed post | Vertical / Square | 4:5 o 1:1 |
| Instagram Stories | Vertical | 9:16 |
| TikTok | Vertical | 9:16 |
| LinkedIn (organic) | Vertical / Square | 4:5 o 1:1 |
| Facebook Reels | Vertical | 9:16 |
| Presentations and trade fairs | Horizontal | 16:9 |
| Desktop display campaigns | Horizontal | 16:9 |
| Mobile advertising (Meta, TikTok) | Vertical | 9:16 |
The multiformat strategy: produce once, distribute everywhere
The most mature and strategic answer to the question “vertical or horizontal?” is not to choose one or the other: it is to plan the production to deliver both.
At Bliss, we work with many clients who, at briefing stage, ask us to optimise their production investment while ensuring maximum coverage across all channels. The solution is dual-format shooting: from the shoot itself, the director of photography frames with both aspect ratios in mind, keeping the main subject at the centre of the frame, where it will be visible in both the 16:9 and the 9:16 crop. Channel-specific versions are then created in post-production.
This approach makes it possible to:
- Maintain narrative and visual consistency across all touchpoints;
- Optimise the production budget by avoiding separate shoots;
- Adapt the editing to the logic of each platform (a faster pace for vertical social content, a more elaborate one for institutional horizontal content);
- Meet the expectations of algorithms and users on each channel.
Case studies and insights from Bliss video production
16:9 corporate video with social adaptation
In several campaigns for brands in the fashion, food and B2B sectors, Bliss has adopted a production pipeline that starts from a 16:9 master, optimised for the website and YouTube, from which vertical and square cuts are derived for social channels. This has enabled clients to cover their entire digital ecosystem with a single, coordinated production investment.
If you are weighing how much to invest in your next video production, we recommend reading our complete guide: Promotional Video: What It Is, Effective Types and Cost Guide [2026], an essential resource for planning your budget with full awareness.
Time as a variable in choosing the format
The choice of format also affects production timelines: content designed for vertical, often shorter and geared to a single platform, has a different post-production pipeline from a structured 16:9 corporate video. Explore the topic further in our guide: How long does it take to produce a corporate video? Timelines, stages and variables to consider.
Length and format: a two-way relationship
The vertical format tends to favour short content: brevity is imposed by the very nature of the platforms that host it (TikTok, Reels, Shorts). The horizontal format, by contrast, is better suited to structured content capable of sustaining minutes of narrative.

Ultra-wide vertical and the cinematic format on social media
Instagram has recently introduced the option to publish Reels in ultra-wide format (5120×1080 pixels), a cinematic aspect ratio that breaks the monotony of the vertical feed and brings a filmic aesthetic to social media. Some agencies expect this novelty to become established, while others interpret it as an early sign of hybridisation between cinematic and social language AP Consulting srl, a trend worth watching.
Luxury brands and cinematic production
Luxury brands are redefining the standards of video production, adopting the language and aesthetic codes of cinema. It is not just a matter of choosing the right format, but of building a coherent, premium visual identity that works regardless of proportion. Explore this phenomenon in our article: Why and how luxury brands are becoming film production studios.
Still life and video: the convergence of formats
In the premium and luxury sector, the line between still life photography and video is becoming thinner. Hybrid productions, which combine the visual precision of stills with motion sequences, are gaining ground as brand storytelling tools. The choice of video format is inevitably intertwined with the choice of photographic format. Find out how to optimise your brand’s visual communication: Luxury Still Life: A Guide to Elevating a Brand.
The algorithm rewards vertical, but context is everything
In 2026, Facebook’s algorithm clearly favours vertical content, and although 16:9 is still technically supported, vertical is now the winning format for organic reach Webeing. But this does not mean that 16:9 is obsolete: it means that each format must be used in the right context. Brands that produce only vertical content lose authority in institutional settings; those that produce only horizontal content lose reach and relevance on social media. The winning strategy is complementarity.
Subtitles as a multi-format design element
Videos with AI-generated subtitles that dynamically emphasise keywords reduce skip rates to 14.7% and improve brand recall by 34.2% Amra & Elma. In 2026, subtitles are not a technical add-on: they are an integral part of video design, especially in vertical format, where viewing without sound is the norm. Designing lettering and subtitles to fit the format, rather than the other way round, is one of the new skills of strategic video production.
FAQ: frequently asked questions about video format
Can I upload a horizontal video to Instagram Reels? Technically yes, but it is strongly discouraged. Instagram will automatically add black bars to the sides (letterboxing), drastically reducing visual impact and penalising the content’s algorithmic distribution. For Reels, the native format is 9:16.
What is the best format for a corporate video? It depends on its primary use. If the video is intended for the website, YouTube, events or corporate presentations, 16:9 is the right choice. If the primary objective is social distribution, 9:16 is preferable, or produce both versions.
Does the vertical format work for B2B too? Increasingly so. LinkedIn is shifting towards vertical content: according to the latest data, 97% of videos on LinkedIn are in vertical format and 78% are shot on a smartphone rather than with professional equipment SellersCommerce. In B2B too, authentic, mobile-first communication is gaining ground.
Is it better to produce two separate versions of the video or to adapt it in post-production? The most efficient solution is to plan for dual format from the shooting stage. Adapting in post-production a video not designed for vertical almost always leads to cropped images, subjects partly out of frame or poor composition. The investment in proper planning during pre-production pays for itself immediately.
What is the aspect ratio for LinkedIn? For organic posts on LinkedIn, the 4:5 (vertical) or 1:1 (square) format performs better than the traditional 16:9, especially on mobile. For advertising campaigns, 9:16 is the recommended format.
Does the vertical format reduce the perceived quality of a video? Not if the production is conceived natively for vertical. A well-produced vertical video, with composition, lighting and editing optimised for the 9:16 aspect ratio, has very high perceived quality. The problem arises when content conceived for 16:9 is adapted in post-production without rethinking the composition.
How much does it cost to produce a video in both formats? The additional cost of a multi-format version is generally modest if properly planned in pre-production: it is mainly a post-production and editing cost. The opposite approach, producing two separate pieces of content, costs considerably more. For a tailored estimate, see our guide to video production costs.
