What Aspect Ratio Should You Use for Art Videos on Instagram, TikTok and YouTube?

For art videos on Instagram Reels, TikTok, and YouTube Shorts, the recommended format is 9:16 at 1080 x 1920 pixels. Instagram feed videos suit 4:5, while longer YouTube and portfolio videos suit 16:9.

An incorrect art video aspect ratio can crop a signature, shrink a composition, or surround the work with black bars, undermining hours of careful craft. Because each platform is built around a specific format, mismatched content is routinely cropped, scaled down, or letterboxed. Choosing the correct frame before you edit protects your composition and presents your work as intended.

This guide outlines the ideal ratio for each platform, the reasoning behind each choice, and the framing practices that keep your artwork professional and fully visible on any device.

• Use 9:16 at 1080 x 1920 px for Reels, TikTok, and YouTube Shorts.
• Use 4:5 for Instagram feed videos and 16:9 for long-form YouTube.
• One vertical export works across all three short-form platforms.
• Keep key details in the center, away from captions and buttons.
• Preview on a real phone before you post.

For artists, this matters more than for most creators. The wrong frame can cut off a corner you spent hours refining. Tall frames suit portraits naturally, while wide paintings need more care.

Aspect ratio is the proportion between the width and height of your video, written as width:height.

• 9:16: Tall and narrow, like a phone held upright.
• 16:9: Wide, like a traditional screen.
• 1:1: A perfect square.

9:16 is the default for short-form art video. Instagram Reels, TikTok, and YouTube Shorts are all built around full-screen vertical viewing, so a vertical art video fills the whole phone screen with no wasted space.

The table below covers the most common sizes.

Platforms update their specs from time to time, so check current guidelines before an important upload.

How Big Should an Instagram Reel Be?

The ideal Instagram Reel size is 1080 x 1920 pixels in a 9:16 ratio. A square or horizontal upload is placed inside the vertical frame with empty bars above and below, which leaves your artwork looking small.

• Reels: 9:16 is the target and the safest choice for reaching new audiences.
• Feed posts: 4:5 portrait takes up more vertical space as people scroll. Square 1:1 also works well.
• Stories: 9:16, with interface elements at the top and bottom that can cover your art.

Profile grids also show previews in a cropped shape, so choose a cover frame that keeps the most interesting part of the artwork in the center.

What Is the Best Video Size for TikTok Art Videos?

The best TikTok video size is 1080 x 1920 pixels at 9:16, the same as Instagram Reels. TikTok places your username, caption, and music information along the bottom, with action buttons down the right side.

If your artwork reaches the bottom edge, the caption will sit on top of it, so keep important details inside the central area of the frame.

Can One Vertical Export Work for YouTube Shorts Too?

Yes. The standard YouTube Shorts dimensions are 1080 x 1920 pixels at 9:16, so a single vertical export can be reused across Reels, TikTok, and Shorts with little or no change.

YouTube also uses aspect ratio to classify uploads. A vertical video within the supported length limit is eligible for the Shorts feed, while a horizontal 16:9 video is treated as a standard video. For a longer process video, such as a full-speed painting with commentary, 16:9 at 1920 x 1080 pixels remains the right choice.

Follow these six steps to get the right frame from the start, instead of fixing it after editing.

Step 1: Decide where it will live first: Pick the main platform before you edit. For short-form platforms, start with 9:16.

Step 2: Check your artwork's shape: Note whether your artwork is portrait, landscape, or square, so you know how much you will need to crop or pad.

Step 3: Set the canvas before you edit: Create your project at 1080 x 1920 pixels instead of resizing after you place your clips.

Step 4: Frame inside the safe area: Keep the main features away from the top, bottom, and right edges, where captions and buttons sit.

Step 5: Add a simple background if needed: If your artwork is wider than the frame, place it on a clean, neutral background rather than stretching it.

Step 6: Export and preview on a phone: Watch the file on a real phone before posting to see how the interface sits over your work.

A few simple framing habits keep your artwork complete and professional on any screen.

• Keep the main subject in the center third of the frame.
• Use a plain background in a color that complements the piece.
• Never stretch a landscape artwork to fill a vertical frame.
• Export at the highest resolution the platform accepts.

Think of the frame as a small window on a phone. Whatever sits outside the center is the first thing to get covered or cut off.

Most framing problems come from small, avoidable choices, not from the artwork itself. Check your video against this list before you post.

• Uploading a 16:9 video to a vertical platform, leaving a tiny image between black bars.
• Placing the signature or final details at the bottom edge, where captions will cover them.
• Stretching or squashing artwork, which distorts its proportions.
• Exporting at low resolution, which makes fine linework look soft.

Each of these is easy to fix before you publish. A quick check against this list keeps your artwork sharp, centered, and fully visible.

Getting the ratio right is only part of the job; how you frame your artwork inside it matters just as much. These practical takeaways will help you present your work cleanly on every platform.

• Plan the frame early. Choosing the platform and ratio before editing prevents cropping problems later.
• Think in a safe area. Captions, buttons, and interface elements cover the edges, so central placement protects your work.
• One export, many platforms. A single 9:16 file at 1080 x 1920 pixels works across Reels, TikTok, and Shorts.
• Never stretch to fit. A clean, neutral background keeps proportions true when artwork does not match the frame.
• Test on a real device. A phone preview shows exactly how the interface sits over your art.

The right aspect ratio will not make your art better, but it ensures your art is seen as you intended. For Reels, TikTok, and Shorts, 9:16 at 1080 x 1920 pixels is the dependable standard, with 4:5 for Instagram feed posts and 16:9 for longer YouTube videos. Plan your frame early, keep important details centered, and preview before you post.
