これは元々Peachのウェブサイトに掲載されていたものです。 PeachからCape.ioへのリブランドについて詳しくはこちらをご覧ください。

あなたは今、Cape.ioを使って、必要な全てのアスペクト比で広告をFacebook、Instagram、およびYouTubeに直接送信できます。

広告を最適化するには、最大限の利用可能なスペースを埋める形式で提供し、コンテンツが切り取られるリスクを避けるのが理にかなっています。これは、各プラットフォームの異なる配置や異なるデバイスで異なる場合があります。 

Peachは、最も野心的なソーシャルメディアキャンペーンの要求にも応えるために、複数のアスペクト比を受け入れます (16:9 (横); 1:1 (正方形); 9:16, 3:4, 4:5 (縦))。しかし、考えられる無数のバリエーションがあるため、適切なアスペクト比と仕様を確保することは複雑です。YouTube、Facebook、およびInstagramの推奨アスペクト比に関する簡単なガイドをまとめて、シンプルなワークフローと効果的なソーシャルメディアでの動画を実現しました。

Twitter用のアスペクト比 

Twitterは以下の動画を推奨しています:

  • 16:9

  • 1:1

  • 9:16

以下のアスペクト比も許容されます:

  • 3:4

  • 4:5

Peachはクリエイティブに変更を加えません: アスペクト比を切り取ったり引き伸ばしたりして動画を変更することはありません。

YouTube用のアスペクト比

  • 16:9

  • 9:16

YouTubeでの動画コンテンツは主に16:9の比率で表示されます。これはデスクトップおよびモバイルの標準比率ですが、プラットフォームはモバイルでの閲覧専用に9:16(つまり縦)の形式も受け入れています。

YouTubeの配置

YouTubeは6種類のビデオ広告配置をサポートしています。最も一般的なのはTrueview、前ロール(または中ロール、後ロール)およびバンパー広告です。すべてのYouTube配置では16:9(またはモバイル用に9:16)のコンテンツが必要ですが、コンテンツと長さを最適化したいかもしれません。

前ロール、中ロール、または後ロール: 選択されたビデオコンテンツの前、途中、または後に実行される広告。これらはスキップ可能(つまりTrueview)またはスキップ不可能です。

Trueview: 視聴者が視聴することを選択する広告。これらはビデオが始まる前または途中にインストリームで配置されたり、他のYouTube動画の横に支払った広告として発見されたり、YouTube検索結果で発見されたり、Googleディスプレイネットワークを通じて外部のウェブサイトに表示されます。視聴者が広告をクリックするか、広告を30秒以上視聴した場合に料金が発生します。

バンパー: YouTube動画が始まる前に再生される6秒のスキップ不可動画広告。これらはスキップ不可ですが、簡潔にする必要があります!

FacebookとInstagram

YouTubeとは異なり、FacebookとInstagramはさまざまな配置でさまざまな種類の広告を受け入れるため、多くの異なるアスペクト比を受け入れます。これには以下が含まれます:

  • ニュースフィード

  • インスタント記事

  • インストリームビデオ

  • 右コラム

  • マーケットプレイス

  • ストーリーズ

(Facebookのヘルプセンターで配置に関する詳細をこちらで見つけることができます)。

同じアスペクト比が異なる配置やモバイルとデスクトップ間で機能する可能性があります。しかし、各配置に対する推奨オプション以外のアスペクト比で提供される広告は最適化されません。

言い換えれば、各宛先に対して正しいアスペクト比にフォーマットされている広告は、画面上で最も広告の不動産を提供し、最高の視聴体験を提供し、最終的により効果的なコンバージョンを実現します。

FacebookとInstagram用のアスペクト比

Facebook広告マネージャーは、現在利用可能な完全なアスペクト比のスイートを受け入れます。この便利なテーブルには、Facebook、Instagram、およびオーディエンスネットワークでの異なるエクスペリエンスに使用されるアスペクト比が示されています。

Peachがサポートするアスペクト比は次の通りです (このおすすめの詳細はFacebook広告マネージャーで見つかります):

Facebookで:

  • FacebookとInstagramの両方でのビデオキャンペーン: 4:5

  • リンク無しのFacebookビデオ広告: フルポートレイト(9:16)、ビデオの最も重要な部分がモバイルでのニュースフィード内に2:3のアスペクト比で見える状態。

  • ニュースフィード

    • ビデオカルーセル: 正方形 (1:1)。

    • リンク無し広告: 16:9から1:1まで。

    • 360ビデオ: 1:2(クリック時にフルスクリーン)。

Instagramで:

  • すべてのフィードでのビデオ広告: Peachは1:1と4:5の動画をQCし、両方ともすべてのInstagramフィードでサポートされます。

  • Instagramストーリーズでのビデオ広告: フルポートレート(9:16)

オーディエンスネットワークで

  • インストリーム配置:  1:1とフルランドスケープ(16:9)。

まとめ - FacebookとInstagramでの広告を最適化する最も安全な方法は、4:5のアスペクト比を遵守することです。これはすべてのエクスペリエンスに完全には最適化されませんが、両方のプラットフォームのほとんどの配置内では効果的です。

No more chocolate at breakfast? Navigating the new LHF ad rules this Easter

As ad compliance requirements evolve in 2026, UK confectionery brands face new restrictions on less healthy food (LHF) advertising. With the January 5 watershed now in effect, ad quality assurance systems must validate timing, placement, and product identifiability to avoid clearance failures this Easter season.

The future of inclusion: How Cape.io powered Virgin Media Television’s fully accessible ad break during the Men’s Six Nations

As Channel 4’s closed-captioning mandate came into effect in March 2026, Cape.io partnered with Virgin Media Television, Omnicom Media Group and VoiceBox to deliver a truly accessible ad break during the Guinness Men’s Six Nations. More than ad compliance, this moment proved that accessibility can operate at the highest level of live sports broadcasting.

Navigating Channel 4’s 2026 closed caption mandate

As ad compliance requirements tighten across the UK and Europe, closed captioning has evolved from an accessibility checkbox to a strategic necessity. Whether you're managing CTV campaigns or social media creative, automated ad testing for caption quality is no longer optional - it's fundamental to reaching today's fragmented, multi-screen audiences.

The advertising landscape is facing a seismic shift. By March 1, Channel 4 will become the first UK broadcaster to mandate closed captions across all advertising - including linear TV, streaming, and sponsorships.

The mandate is  a redefined standard for global inclusivity. Here is everything you need to know about the new mandate and how to stay ahead of the curve.

One platform, many realities: How creative automation platforms resolve the global vs. local tension

Scaling global marketing without losing local relevance requires more than brand guidelines and templates - it requires a creative automation platform designed for both global control and local flexibility. Most systems optimize for standardization, but scaling ad creative production across markets demands architecture that enables creative variation and adaptation by local experts without fragmenting brand governance.

Many global advertisers are chasing the same ideal: scale without losing relevance.

Consistency without uniformity.
Efficiency without bureaucracy.

It sounds simple. In practice, it’s one of the hardest tensions to resolve in modern marketing.

The global vs. local challenge isn’t new, but it’s becoming more urgent. As brands expand across markets, channels, and cultures, the question is no longer whether you should scale globally, but how you do so without erasing the nuance that makes marketing effective in the first place.

Everyone is looking for this balance. Very few get it right.

EPTVI Initiative launches Stage Two to help programmatic TV scale across Europe’s largest advertising markets

Broadcasters, streamers, agencies and ad tech companies including Google Ad Manager, Equativ, Adform, LiveRamp, The Trade Desk, FreeWheel and Cape.io begin work on practical solutions to reduce complexity and speed up adoption.

The guardrails of growth: Why creative intelligence demands compliance

Generative AI can produce thousands of creative variants, but most compliance systems are still manual, fragmented, and reactive, unable to keep pace with today’s velocity. To move fast without breaking things, the industry needs a new approach: real-time verification, programmatic enforcement, and end-to-end visibility. Embedded inside the stack, not bolted on at the end.
