How to put two photos side by side on iPhone

Place two photos in one horizontal frame on iPhone, balance mixed orientations, control the spacing, and export a single PNG for X or Threads.

To put two photos side by side on iPhone, import both images into the same ScreenEdit canvas and choose the Horizontal layout. ScreenEdit places them from left to right, keeps each photo’s proportions by default, lets you control the space between them, and exports the finished composition as one PNG through the native iOS share sheet.

You can build the composition in a fixed 16:9, 5:3, 4:3, or 1:1 frame.

Start with the relationship between the photos

A side-by-side image works when the two photos make one point together. They might show two options, two moments, two details, or the same subject under different conditions.

Decide which photo should appear first before styling the frame. In a left-to-right layout, viewers will usually read the left image first. Put the photo that establishes the subject or context there, then place the result, response, or contrast on the right.

Choose the layout that gives both photos the right weight

ScreenEdit offers four multi-image layouts:

  • Horizontal places the photos next to each other and is the direct choice for a side-by-side image.
  • Grid with two columns gives the photos equal-width slots, which can help a balanced comparison.
  • Free lets you position the photos manually when they should overlap or have different visual sizes.
  • Vertical stacks the photos from top to bottom when a left-to-right composition makes them too small.

Horizontal and grid layouts solve slightly different problems. Horizontal fits the images across the canvas according to their proportions. A two-column grid gives each image the same amount of slot width, although the visible photo sizes can still differ when their original shapes differ.

Handle mixed portrait and landscape photos without stretching

A portrait photo and a landscape photo will not fill matching spaces in the same way. ScreenEdit preserves each image’s aspect ratio by default, so it does not need to stretch either photo to make the pair fit.

For mixed orientations, choose what matters most:

  • Use Horizontal when a shared visual height makes the pair feel connected.
  • Use a two-column grid when equal-width positions make the comparison clearer.
  • Keep the complete photos visible and use the background space as part of the design.
  • Crop only when removing part of the source will not change the meaning of the image.

Matching borders, corner treatment, and shadows can make two differently shaped photos feel like one composition without pretending they have the same proportions.

Give each photo equal visual weight

Equal weight does not always mean identical dimensions. It means neither image looks accidental or unimportant.

Start by aligning the photos to a common edge or centre line. Keep their subjects at comparable visual sizes when the pair is a direct comparison. If one photo is naturally brighter or busier, it may look more dominant even when both slots are equal, so judge the complete canvas rather than relying only on measurements.

Use the image order controls if the story reads backwards. The first image belongs on the left in a horizontal layout and in the first grid position.

Set consistent spacing

ScreenEdit has an adjustable spacing control. A small gap clearly separates the two photos, while a larger gap makes the background more visible and gives each image more independence.

Use one deliberate gap rather than trying to position both photos by eye. Also check the outer space around the pair. The distance between the photos does not need to equal the canvas margin, but the two values should feel related.

Pick a frame for the finished pair

  • 16:9 gives two images the most horizontal room.
  • 5:3 keeps a wide composition slightly more compact.
  • 4:3 works when both photos need more height.
  • 1:1 creates a compact square pair, but each photo may appear smaller.

These ratios control the exported composition, not the way every social feed presents it. X and Threads can use different preview treatments, so inspect the attached image before publishing and open it once to confirm the complete pair is present.

A side-by-side workflow on iPhone

  1. Import both photos into ScreenEdit from the Photo Library or Files.
  2. Choose the Horizontal layout, or use a two-column Grid for equal-width slots.
  3. Put the context or first moment on the left.
  4. Align the photos and check their visual weight.
  5. Set the spacing between the images.
  6. Choose a 16:9, 5:3, 4:3, or 1:1 frame.
  7. Apply a consistent background, border, corner treatment, or shadow if it helps unify the pair.
  8. Export the composition as a PNG and share it with the native iOS share sheet.

The finished file should read as one image with two connected parts, not two unrelated photos placed beside each other.
