Aspect Ratio Variations

Upload different versions of your creative optimized for various placements like Feed, Stories, and Reels.

How It Works

When you upload files with matching base names and aspect ratio suffixes (_vertical or _horizontal), Ads Uploader automatically groups them as variations of the same creative. This ensures Meta serves the right format for each placement.

Overview

Meta ads appear across multiple placements with different aspect ratio requirements. By uploading variations of your creative, you ensure optimal display across all placements without cropping or letterboxing.

Naming Format

File Pattern	Description	Placement
`base_file_name.ext`	Main creative	Feed, Square placements
`base_file_name_vertical.ext`	Stories/Reels version	Vertical placements
`base_file_name_horizontal.ext`	In-stream/Desktop version	Horizontal placements

Aspect Ratio Types

Square/Feed (Base File)

Ratio: 1:1 or 4:5
Best for: News Feed, Instagram Feed
Example: product_launch.mp4
Dimensions: 1080x1080px (1:1) or 1080x1350px (4:5)

Vertical (_vertical)

Ratio: 9:16
Best for: Stories, Reels, vertical mobile feeds
Example: product_launch_vertical.mp4
Dimensions: 1080x1920px

Horizontal (_horizontal)

Ratio: 16:9
Best for: In-stream videos, desktop feeds
Example: product_launch_horizontal.mp4
Dimensions: 1920x1080px

Visual Indicators

After upload, you'll see:

V badge for files with vertical associations
H badge for files with horizontal associations
Grouped display showing all variations together

Complete Example Set

File	Type	Aspect Ratio	Placement
`brand_video.mp4`	Main creative	1:1 or 4:5	Feed
`brand_video_vertical.mp4`	Vertical variant	9:16	Stories/Reels
`brand_video_horizontal.mp4`	Horizontal variant	16:9	In-stream/Desktop

Custom Aspect Ratio Suffixes

For teams with different naming conventions, you can configure custom aspect ratio suffixes in User Defaults.

Supported Custom Suffixes

Suffix	Parsed Ratio	Example
`1x1`	1.0 (square)	`product_1x1.jpg`
`4x5`	0.8 (portrait)	`product_4x5.jpg`
`9x16`	0.5625 (vertical)	`product_9x16.mp4`
`16x9`	1.78 (horizontal)	`product_16x9.mp4`
`916`	0.5625 (vertical)	`product_916.mp4`
`45`	0.8 (portrait)	`product_45.jpg`

How Auto-Detection Works

When using custom suffixes, Ads Uploader automatically determines which file is the primary (feed) asset and which are variants:

Primary Selection: The file with an aspect ratio closest to 1.0 (square) becomes the primary/feed asset
Vertical Variants: Files with lower ratios than the primary become vertical variants (Stories/Reels)
Horizontal Variants: Files with higher ratios than the primary become horizontal variants

Example:

Upload product_4x5.jpg (ratio 0.8) + product_9x16.jpg (ratio 0.5625)
Result: 4x5 becomes primary (closer to 1.0), 9x16 becomes vertical variant

Custom Delimiter

You can also change the delimiter between the base name and suffix. Default is underscore (_), but you can use hyphen (-) or other characters.

Delimiter	Example
`_` (default)	`product_9x16.mp4`
`-`	`product-9x16.mp4`

Configure these settings in Account > Defaults > Media Variants.
