Instagram Post Specs: Portrait Feed Images and Reels

Begin by naming the deliverable: a feed photograph or a Reel. Next identify what the viewer needs to see, such as a glaze finish, a handle shape, or a maker’s mark. Those decisions should guide the crop and edit before you choose export settings. A tidy dimensions report is useful, but it cannot tell you whether the important detail survives.

Choose the post route before designing the frame

Imagine a studio introducing a handmade mug. The feed photograph should make the color, handle, and overall proportions easy to judge. The Reel might show the mug turning in a hand, water being poured, or light moving across the glaze. These are different explanations of the same object. Decide which explanation you are making before setting up the canvas, rather than treating a still and a moving sequence as interchangeable exports.

For a single portrait feed image, this checker offers a Preparation target of 1080 by 1350 pixels. For a vertical Reel, it offers a Preparation target of 1080 by 1920 pixels. These are practical working canvases, not claims that every other size is rejected. They help a team agree on an output shape without pretending to describe every choice available in the Instagram composer.

Write the route into the asset brief: portrait feed photo, or Reel video. Include the intended first impression beside it. For the photograph, that might be “show the blue glaze and full handle.” For the Reel, it might be “show how the lid opens.” This small note helps an editor make decisions when an attractive crop hides the very feature the post was supposed to explain.

At handoff, select the corresponding native creation route and inspect its preview. Do not use a video preset merely because the campaign folder also contains photographs, and do not assume a cover image describes the entire Reel. The creation screen is the place to review the actual post treatment. The local checker describes the file you supplied; it does not select that route or confirm the account’s available controls.

Make a portrait still answer a product question

A useful product image answers a concrete question. For the mug, the question could be whether a finger fits comfortably through the handle. Give that feature enough room to read without zooming. A centered object is not automatically a clear object: the handle may merge into a dark background, or a label may face away from the camera. Solve those problems in lighting and composition before worrying about the final pixel count.

Build the portrait layout around a hierarchy. The object comes first, the identifying detail comes second, and any added text comes last. If a heading needs to sit above the mug, reserve that space intentionally. Shrinking the product after adding a large heading can turn a detail photograph into a poster with an indistinct object. Often the strongest correction is removing words rather than increasing the canvas or sharpening the export.

Review the image at a size similar to ordinary phone viewing, not only at full size in the design application. Can you distinguish the edge of the handle? Can you tell whether a bright patch is glaze or reflected lighting? If the maker’s mark matters, use a separate detail composition rather than expecting a tiny stamp to carry the whole story. Readability is an editorial judgment, not a value the checker can calculate.

Keep a version without baked-in promotional text. That clean photograph gives you room to change the layout later, create a different crop, or use the image in another asset without repainting the background. If text remains in the final still, inspect its contrast over both bright and dark areas. Export a sample early and open that sample independently; the design application’s preview is not the file your colleague will receive.

Reframe the action for a Reel rather than stretching the still

A Reel needs a sequence that stays understandable over time. Start with the mug already visible, then show the action that explains it. If the purpose is to demonstrate a snug lid, the viewer needs to see the lid before, during, and after the movement. A decorative opening shot of the studio may look polished but leave less room for the demonstration. Trim material according to the explanation, not simply to make the file shorter.

Use the vertical preparation canvas as a framing plan. Leave room for the hand to enter, the lid to rise, and the object to turn without losing important edges. Check more than the opening frame. A handle that is safely inside the frame at the start can disappear when the mug rotates. Move through the exported clip at its most active moments and watch for those changing boundaries.

Do not turn a portrait photograph into a Reel by stretching it to fill a taller rectangle. Stretching changes the object’s proportions; enlarging it proportionally may cut off useful information. If a still is part of the sequence, place it deliberately, use a suitable background, or redesign that shot. Better yet, capture a short moving view specifically for the action. The source should support the story before the export preset is applied.

Review captions and on-screen labels where the action occurs. A label saying “twist to open” should not cover the fingers demonstrating the twist. The Video Safe Zone Checker can help you plan overlay clearance, while the native preview remains necessary for the actual interface. Neither a safe-zone layout nor this specs check certifies that every viewer will see the same unobstructed frame.

Protect the master and make named derivatives

Keep the original photograph or editing project separate from the delivery files. Suppose the studio’s photograph is 4000 by 6000 pixels. Its width-to-height ratio is two thirds, so it is not the same shape as the 4:5 feed preparation target. You can choose a crop from the master while preserving the original framing for later work. Overwriting the source with the first social export removes that useful flexibility.

For a 4:5 crop that uses the full 4000-pixel source width, the corresponding height is 5000 pixels. The difference from the original height is 1000 pixels. A centered crop would remove 500 pixels from each end, but that is only a starting position. Move the crop if the mug’s rim or a meaningful shadow needs more space. Then resize the chosen crop to the 1080 by 1350 preparation canvas.

A 9:16 crop using the full 6000-pixel height of that same photograph would be 3375 pixels wide. It removes substantially more material from the sides than the feed crop. That calculation explains why a hand or handle may disappear when you repurpose a still for vertical video. It does not mean the taller derivative is wrong; it means the composition needs a second decision, rather than a blind change of export dimensions.

Give each output a clear role in its name, such as mug-blue-feed-portrait-v03 and mug-blue-reel-demo-v02. Store the clean master, feed crop, Reel project, and final video as distinct items. A reviewer should be able to identify the approved deliverable without opening every file. When a correction is requested, record whether it affects only one derivative or should also be applied to the original color treatment and future exports.

Check the exported pixels, not the preset label

Export presets are convenient, but their names are not evidence. A preset called “Instagram portrait” may have been created for a different asset or changed by another editor. Open the completed file and inspect its width and height. The checker calculates aspect ratio from those dimensions. A 1080 by 1350 image has a width-to-height ratio of 0.8; a 1080 by 1920 video has a ratio of 0.5625.

A smaller file can keep exactly the same shape. An 864 by 1080 image is also 4:5, although it is below the chosen feed preparation canvas. That difference calls for a visual review, not an automatic declaration that the upload is invalid. Look at the source detail, intended crop, and native preview. Enlarging a soft image merely to match the target creates more pixels without recovering missing texture or making small lettering genuinely sharper.

Use the optional file picker when the browser can read the export. If you enter dimensions manually, take them from the final media file rather than the editing timeline. A timeline can be vertical while an export is accidentally landscape. If the browser cannot read a video, manual values still let you compare geometry, but label them honestly as manual. They are not a hidden inspection of the file’s encoding.

For a still that needs a deliberate size change, use the Image Resizer after choosing the crop. The specs checker does not crop or resize media. Recheck the newly exported derivative, since a correct intermediate file does not prove the delivered version is identical. This is particularly useful when a colleague exports again, changes a format setting, or receives the file through a service that may create another copy.

Read the report as a preparation review

Separate three questions when reading the result. What dimensions does the file have? How does that geometry compare with the selected preparation canvas? Which published numeric constraints, if any, are actually checked? These questions have different answers. A target comparison can say the file is different without establishing that Instagram will reject it. Conversely, a matching canvas says nothing about whether a label is legible or the demonstration is useful.

The Instagram formats in this reference deliberately omit unverified numeric limits. Official help was inaccessible during this research session, so the records do not turn familiar file-size or duration figures into hard rules. Missing checks are visible limits of the reference, not permission to assume an unlimited upload. Review the current options in the composer you intend to use, especially when the file differs substantially from your normal workflow.

File size can still be recorded as an observation. A 12,500,000-byte export corresponds to 12.5 decimal MB because this tool uses one million bytes per MB. That conversion is not an Instagram maximum. Similarly, the checker’s own local processing guard is a tool resource limit, not a published platform rule. If a file is too large for local inspection, manual measurements can describe it without pretending that the native composer has already accepted it.

Copy the report into the asset review with a short human note: “feed crop checked; handle clear; native preview still needed.” That note is more actionable than a vague “ready” label. The checker does not test codec, frame rate, audio, account eligibility, or exact display treatment. Keep those unknowns separate from the dimensions you measured, and ask the person completing the post to confirm the remaining visual decisions.

Review the native preview with the export beside you

Bring the delivered file into the intended Instagram creation flow and compare its preview with the export you reviewed. For the photograph, inspect the full product silhouette and any selected crop. For the Reel, play through the movement rather than judging the cover alone. If the preview changes the framing, determine whether the change is a selected crop, a different asset, or a display treatment before returning to the editor for a new export.

Use a short visual checklist tied to the brief. The mug handle is complete, the rim is visible, the blue glaze remains distinguishable, and the explanatory text does not cover the feature. For the Reel, add whether the lid movement is understandable and whether the clip starts and ends cleanly. These are specific review questions. They help two colleagues agree on a correction without arguing over an undefined impression of quality.

Treat the caption as a separate deliverable. A baked-in image heading cannot stand in for the full post text, and a polished caption cannot repair an unreadable product label. Keep the final caption next to the approved filename and use the Social Media Character Counter for a separate text review. This preserves the distinction between what is inside the media and what is entered into the post fields.

When a revision is necessary, change the smallest thing that solves the observed problem. If the handle is cropped, adjust framing. If the glaze looks muddy, revisit the image treatment. If the Reel pauses too long before the action, revise the edit. Exporting every version at a larger resolution is not a general solution. Reopen the revised output, check it again, and make sure the handoff now names the replacement rather than the superseded file.

Deliver a small, unambiguous asset package

A useful delivery package contains only the approved items and the information needed to use them. For the studio campaign, include the portrait feed image, the Reel video, the caption document, and a note identifying the intended route for each. Keep editable projects elsewhere, clearly associated with the campaign. Mixing source photographs, experimental crops, and final exports in one upload folder invites a perfectly measured but unintended file to be selected.

Record the preparation choice in plain language: “feed still uses the 4:5 preparation canvas” and “Reel uses the vertical preparation canvas.” Add any unresolved issue, such as a detail that needs a native preview. Do not translate the target comparison into an approval guarantee. A colleague should understand both what was reviewed and what still requires attention, without reopening the checker or reconstructing the export decisions from memory.

For repeat campaigns, add asset roles to the Content Calendar Generator: photograph, demonstration video, caption, and review owner. This organizes the work without forcing every post to look alike. A future product may need a wider composition or a different explanation. Preserve the process of deliberate preparation, not an inflexible template that makes every object fit the same frame regardless of its shape.

Finish with a simple separation of responsibilities. The file review establishes observed geometry and practical presentation choices; the person completing the post checks the current native treatment. Return to the checker for a revised export or browse the free tools directory for the next task. The goal is a clear product asset with a traceable handoff, not an impressive-looking report that leaves the actual object difficult to see.
