Should I post square or portrait on Instagram in 2026?

Portrait (4:5, 1080×1350). It's Instagram's default format and takes up more screen space than square, which improves visibility and dwell time. Square still works but has no advantage.

What resolution should I upload for Instagram?

1080 pixels wide is Instagram's display width and the safest upload size. Uploading higher-resolution images doesn't improve display quality — Instagram resizes them down, which adds a compression step.

Do Instagram Stories and Reels use the same dimensions?

Yes, both are 1080×1920 (9:16). The difference is in the safe zones — Reels have more UI overlay at the bottom for captions and engagement buttons, so keep important elements higher in the frame.

Can I use the same photo for Instagram and DoorDash?

Not without re-cropping. Instagram feed uses 4:5 portrait; DoorDash requires 16:9 landscape. Export separate crops from the same high-resolution original.

Why do my Instagram photos look worse after posting?

Instagram compresses all uploads. Uploading at exactly 1080 pixels wide, using high-quality JPG (not maximum), and starting with a sharp, well-lit photo all reduce visible compression loss. One photo, every platform's dimensions.

Instagram Photo Size for Restaurants 2026: Every Dimension

The most important Instagram dimensions for restaurants in 2026: feed posts are 1080×1350 pixels (4:5 portrait) — this is now Instagram's default and takes up the most screen space in the feed. Stories and Reels are 1080×1920 (9:16). Square 1080×1080 posts still work but occupy less vertical space, which means less attention.

Here's the complete reference, plus what actually matters beyond the numbers.

What are the current Instagram image dimensions?

Format	Dimensions	Aspect ratio	Notes
Feed post (portrait)	1080 × 1350	4:5	Default in 2026 — best feed presence
Feed post (square)	1080 × 1080	1:1	Still supported, less screen space
Feed post (landscape)	1080 × 566	1.91:1	Smallest footprint, generally avoid
Stories	1080 × 1920	9:16	Full screen vertical
Reels	1080 × 1920	9:16	Same as Stories
Reels cover	1080 × 1920	9:16	Displays as 1:1 crop in profile grid
Profile picture	320 × 320	1:1	Displays as a circle
Carousel	1080 × 1350	4:5	All slides must share the same ratio

File specs: JPG or PNG, maximum 30MB per image, RGB color mode.

The key change for 2026: Instagram made 4:5 portrait the default feed format. Portrait posts occupy roughly 35% more vertical screen space than square posts, which directly translates to more attention as users scroll. If you're still posting square, switching to 4:5 is one of the easiest reach improvements available.

What are the safe zones for Instagram Stories?

Instagram Stories are 1080×1920, but not all of that space is usable. UI elements overlay the top and bottom of the frame.

Top 250 pixels: reserved for your profile picture, username, and the story progress bar
Bottom 250 pixels: reserved for the reply field, share button, and (on Reels) the caption
Safe center zone: 1080 × 1420 pixels

Keep any text, logos, prices, or important visual elements inside the center safe zone. A price or menu item name placed in the bottom 250 pixels will be partially hidden behind the reply field.

For Reels specifically, the bottom safe zone is larger — the caption, audio attribution, and engagement buttons take up more room. Keep critical elements in the center 60% of the frame.

Why do 4:5 portrait posts perform better than square?

Two reasons, both about attention.

Screen real estate. A 4:5 portrait post fills significantly more of a phone screen than a 1:1 square. More screen space means more time in view as someone scrolls, and more visual weight relative to the surrounding content.

Instagram's algorithm rewards dwell time. The longer a user looks at a post, the stronger the engagement signal. Larger posts naturally accumulate more dwell time. This isn't a hidden boost for portrait — it's a downstream effect of taking up more room.

The practical implication for restaurants: shoot your food photos in portrait orientation, or crop them to 4:5 before posting. If you're shooting a dish knowing it'll be a feed post, frame it vertically.

How do Instagram dimensions differ from delivery app requirements?

They're all different, which is the frustrating part of running a restaurant across multiple platforms:

Platform	Required ratio	Minimum size
Instagram feed	4:5	1080 × 1350
Instagram Stories/Reels	9:16	1080 × 1920
Facebook feed	4:5 or 1:1	1080 × 1350
DoorDash	16:9	1400 × 800
Uber Eats	5:4	1200 × 800
Google Business Profile	4:3	720 × 540

Six platforms, five different aspect ratios. This is why the same photo can look great on Instagram and get rejected on DoorDash.

The workflow that avoids the headache: shoot at the highest resolution your phone produces, keep the original uncropped, then export a separate crop per platform. When you crop, keep the dish centered enough that a wider or narrower crop still contains the whole subject.

Tools that handle this automatically save real time. PlateShot generates platform-ready crops from a single enhanced photo, so one upload produces the right dimensions for each destination.

Does Instagram compress my photos?

Yes. Instagram compresses all uploads, and the compression is more aggressive on larger files.

To minimize quality loss:

Upload at exactly 1080 pixels wide — Instagram's display width. Uploading wider images forces additional resizing on top of compression.
Use JPG at high quality (85–95%) rather than maximum. Maximum-quality JPGs get compressed harder.
Avoid uploading through third-party apps that pre-compress. Uploading directly through Instagram or a scheduler with a proper API integration produces better results.
Don't add heavy grain or noise — compression handles noise poorly and it turns into visible artifacts.

Sharp, well-lit photos survive compression better than dark or soft ones. Good lighting at capture time is the single best defense against visible compression.

How many photos should a restaurant post per week?

Four to five posts per week is the baseline for consistent algorithmic performance in 2026. That breaks into roughly:

2–3 feed posts (dish spotlights, specials, new menu items)
3–5 Stories (behind the scenes, prep, daily specials)
1–2 Reels (short video — a pour, a cheese pull, a plating sequence)

Consistency matters more than volume. A restaurant posting four times weekly, every week, will outperform one posting ten times one week and nothing the next. Our restaurant social scheduling guide covers how to batch this into a single weekly session.
