Detailed research
Why Users Compare
Adobe Express ranks naturally for Instagram resizing and has explicit 4:5 guidance. A TextFaker alternative can compete only by being narrower: exact crop preview, no design account requirement, and unambiguous numeric output.
- Show 4:5 feed frame and optional square/grid preview.
- Warn when a subject near the edge may be cropped by a centered crop.
- Offer copyable output specs for handoff.
Implementation Notes
Use object-fit style calculations in pure code: cover mode crops to 4:5, contain mode pads to 4:5. Tests should cover both modes and compare canvas dimensions exactly.
- Cover mode: crop source to 4:5 before scaling.
- Contain mode: scale full image into 4:5 canvas with matte padding.
- Validate no visual-taste decisions are required for pass/fail.
Demand Evidence
The photography community source shows people dislike losing composition to Instagram's vertical crop. The marketing community source shows newer grid dimensions add confusion beyond the final feed view.
- This supports showing both final post crop and grid-style thumbnail preview.
- The tool should avoid promising exact Instagram UI behavior beyond documented or tested ratios.
SEO Angle
Search intent is likely practical and urgent: users want to know whether a photo will fit before posting. Page copy should use phrases like 4:5 Instagram crop preview, 1080 x 1350 preview, and Instagram feed crop checker.
Research notes
- Adobe Express states that Instagram vertical posts use a 4:5 ratio and that posts will be cropped to a square shape in the feed, requiring users to keep the subject near the center.
- The TextFaker page should frame the tool as an open-source-powered workflow for deterministic crop preview, not as a full Adobe Express replacement.
- User discussion confirms that feed and grid crops create practical composition problems.
