Creator Content Size Guide 2026: Instagram, TikTok & Campaign Asset Checklist

Creators and independent brands lose time when every post is designed as a separate project. A better system starts with a small set of master canvases, then plans photography, video and graphics so one campaign can produce assets for multiple placements.

This 2026 reference focuses on practical production sizes and a reusable campaign checklist. Platform requirements change, so verify final ad-specific specifications before trafficking paid media.

The three master canvases to build first

For TikTok advertising, TikTok's current Global App Bundle specifications recommend vertical 9:16 video at at least 720 × 1280 px; horizontal 16:9 at at least 1280 × 720; and square 1:1 at at least 640 × 640. The same specification lists MP4, MOV, MPEG and AVI among supported video types for that placement. See TikTok Business Help Center.

Why 1080 × 1920 should be in every creator's system

A 1080 × 1920 vertical master is a 9:16 canvas with enough resolution for common full-screen mobile workflows. It also gives designers a consistent starting point for typography, captions, product framing and motion graphics instead of rebuilding the composition for every edit.

Do not assume one export is accepted by every ad placement. Organic posting tools, paid placements and third-party schedulers can impose different limits. Keep the high-quality master and create delivery exports from it.

The one-shoot campaign asset checklist

Before a campaign shoot ends, try to capture enough material to produce the following:

Photography

• 1 hero vertical portrait
• 1 hero horizontal image
• 3–5 medium product/lifestyle frames
• 3–5 detail images
• 1 clean product-only frame
• Negative-space versions for headline placement

Video

• 5–10 second opening hook
• 15–30 second primary vertical edit
• Several 2–5 second detail clips
• Wide establishing shot
• Close product/detail shot
• Natural audio or room tone when useful
• Clean clips without baked-in text for future reuse

Graphics

• Launch announcement
• Product/detail card
• Release-date asset
• Quote or campaign statement
• Square archive tile
• Website hero crop

This turns one production day into a content library instead of a single post.

Safe-zone thinking: design for interface overlays

Vertical social interfaces place captions, account information and controls over the content. Rather than putting essential text against the extreme top, bottom or edges, keep the subject and critical message closer to the visual center and test the final export inside the destination app before publishing.

For paid campaigns, use the platform's current placement preview because interface treatment can differ by placement and device.

Build a master-first file structure

A clean project structure prevents content from becoming impossible to find after the launch:

CAMPAIGN_NAME/
01_BRIEF/
02_RAW_PHOTO/
03_RAW_VIDEO/
04_MASTERS/
05_VERTICAL_9x16/
06_SQUARE_1x1/
07_LANDSCAPE_16x9/
08_WEB/
09_FINAL_DELIVERY/

Use descriptive filenames such as brand_campaign_asset_ratio_v01.ext. Example: iis_launch_hero_9x16_v03.mp4.

Export once, preserve the master

Keep an editable master and avoid repeatedly downloading and recompressing files from social platforms. Re-export from the original project when a new crop or placement is needed. This protects image quality and makes revisions much faster.

Creators who also release music: keep cover art separate

Social campaign canvases are not substitutes for music-delivery artwork. Spotify currently requires cover art to be square, 1:1, between 640 and 10,000 pixels wide and tall, in TIFF, PNG or JPG with lossless encoding and sRGB 24-bit color. Spotify also advises against upscaling. See Spotify cover-art requirements.

Apple's current Video and Audio Asset Guide recommends album cover art at 3000 × 3000 px, with a 1400 × 1400 minimum, square 1:1, RGB, JPEG or PNG. See Apple Video and Audio Asset Guide.

For a dedicated music-artwork reference, use ii syndicate's Album Cover Size Guide. If you need the artwork itself, see Album & Mixtape Cover Design.

A reusable 12-asset campaign deliverable template

1. Vertical hero video
2. Vertical cutdown A
3. Vertical cutdown B
4. Hero still
5. Product/detail still
6. Square campaign tile
7. Launch-date graphic
8. Story/vertical announcement
9. Website hero image
10. Email/header crop
11. Behind-the-scenes asset
12. Archive image with campaign title/date

A small brand does not necessarily need all 12 for every release. The template is a planning menu: decide the distribution channels first, then capture the raw material needed to create the selected assets.

When to hire content support

If a campaign has a product launch, release date, collaboration or paid-media component, consistent art direction and export discipline become more valuable. ii syndicate's Social Media Content Creation service is built for creators and brands that need campaign-ready content rather than isolated posts. For broader identity work, see the Brand Identity Package.
