Custom Layout Builder: Design Any Grid You Want

In the Layout panel, switch the toggle from Preset to Custom. You get two number inputs — Rows and Columns — and a live grid preview below them. Each supports 1 to 8, so the builder can produce anything from a single frame up to an 8×8 grid of 64 cells.

The grid preview is interactive. Tap one cell, then tap a second cell, and the whole rectangle between them merges into one large block. Tap a merged block again to split it back into single cells. The counter under the grid shows exactly how many photo slots the current layout will create, and Reset grid returns every cell to its own slot.

When the layout looks right, press Apply Layout. The builder hands the shape to the canvas, which fills each slot with your photos in reading order — left to right, top to bottom — so slot order stays predictable no matter how you merged the cells.

Want to follow along as you read? Open the Custom layout builder — the link drops you straight onto the Custom tab so you can test each idea below.

Uniform grids are the simplest: set 3×3 for a classic nine-grid, 2×2 for four photos, or 1×5 for a vertical strip. If you never merge a cell, the builder behaves like a clean preset grid at any size up to 8×8.

Merging is where it gets powerful. Merge the top row of a 3×3 into one block and you get a wide hero image above six thumbnails — a feature layout. Merge a 2×2 square inside a 4×4 grid to create a large focal point surrounded by details, the classic magazine collage. Merge an entire row or column to build panorama bands or a tall sidebar next to a stack of smaller frames.

Because merges always form rectangles, the result stays clean and printable. You can combine several merges in one grid — for example a large top-left block, a wide bottom banner, and a column of small frames on the right — to compose an asymmetric layout that still lines up perfectly.

Start from the photo you want to feature. Decide which image is the hero, give it the largest merged block, and let the remaining cells hold supporting shots. Building around one focal point reads better than a grid of equal squares.

Match the merged block's shape to the photo inside it. A wide block wants a landscape photo; a tall block wants a portrait. Merging cells to fit the image beats cropping a photo to fit a square, especially for faces and product shots.

Keep the slot count close to the number of photos you actually have. Empty slots leave gaps, and a 6×6 grid you can't fill will look sparse. If you are unsure how many photos suit a shape, the nine-grid guide and the composition rules for collages both help you decide before you build.

Presets are faster when your photo count matches a standard shape — four squares, a nine-grid, a simple strip. Reach for the builder when the message needs emphasis: one photo that must be larger than the rest, a panorama that should span the full width, or an odd count like five or seven that no tidy preset covers.

The builder also helps when a preset is almost right but one cell is in the wrong place. Instead of settling, set the same rows and columns as the preset and merge the cells you want combined. You keep the familiar structure and add exactly the emphasis you need.

If you find yourself building the same custom shape repeatedly, save it as a starter project in the local library so future collages begin from your layout instead of a blank grid. The local project library guide covers how saved projects work.

Rows and columns define the underlying framework, and every merge happens inside that framework. A 4×4 grid gives you sixteen equal cells to work with; merging four of them into a 2×2 block leaves thirteen slots total. The slot counter always reflects the real number after merges, so you can size your photo selection to match.

Merges only ever consume single cells, which is why every block stays a clean rectangle. You cannot create an L-shape or a staircase, and that limit is deliberate — it guarantees the layout prints and exports without distorted cells or awkward gaps.

If a merge does not behave as expected, the second cell you tapped probably crossed an existing block. Split that block first, or press Reset grid and start the merges again from a clean framework.

Feature-and-thumbnails: set 3×3, merge the top row into one wide block, and drop your best shot there with eight supporting frames below. Great for event recaps and product highlights.

Magazine focal point: set 4×4 and merge the center four cells into a 2×2 block for a large central image ringed by twelve small ones. Works well for mood boards and travel stories.

Panorama with captions: set 3×2, merge the entire top row into a wide banner for a landscape or group shot, and leave the bottom three cells for detail images. For platform-specific dimensions, pair this with the resizing guide.

Pick seven photos where one is clearly the strongest. Open the Custom tab, set 3×3, and merge the top row into one wide hero block. Confirm the slot counter reads seven, then press Apply Layout and place the hero shot in the wide block.

Now rebuild the same set as a magazine layout: reset the grid, set 4×4, and merge the center four cells. Notice how the same photos feel different when the focal point moves from the top to the middle.

Preview both at phone size and keep the one where the hero image reads first and the supporting shots stay legible. Save the winner as a starter project so your next collage of this type begins from the layout, not a blank grid.

When you move from planning into editing, make only one major decision at a time: image count, layout, crop, spacing, background, then export. Changing all of them together makes it hard to understand what improved the result.

Use the first draft as a diagnostic tool rather than a final design. If it feels weak, identify whether the weakness comes from image choice, layout hierarchy, or finishing details. Each problem requires a different fix.
