Lover Snap

Canvas ratio: 1:1, 4:5, 9:16, and when to use each

Canvas ratio

Lover Snap supports four canvas ratios. Picking the right one upfront is more effective than cropping after.

1:1 (square)

The Instagram grid ratio. Use for:

4:5 (portrait — the default)

This is the default canvas. Use for:

This is the ratio most reference-photo training data is biased toward, which is why faces tend to compose most naturally at 4:5.

9:16 (vertical / phone)

Same ratio as a phone screen. Use for:

9:16 gives the most space for showing a setting — wide background, sky, beach, or a room your subject is standing in.

3:2 (wide portrait — printable)

Closer to traditional photographic print ratios. Use for:

Picking ratio for memorial photos

For memorial photos that may end up in a printed family album or framed on a mantel, 3:2 is the most forgiving ratio. The AI tends to compose a more dignified shoulder-up portrait at 3:2 than at the more selfie-coded 4:5 or 9:16.

Related questions

Can I crop after generation?
Yes — but generating at the destination ratio gives noticeably better composition. The AI frames the subject for the canvas it knows about.
Does ratio affect generation time?
Negligibly. 9:16 takes about 1-2 seconds longer than 1:1 on average.
Why doesn't Lover Snap offer 16:9 landscape?
We rarely generate scenes where the subject reads well in horizontal landscape — phone-first composition is the dominant use case. We may add 16:9 later if memorial wedding-photo demand justifies it.
