Instagram Grid Layout Planner - Visual Feed Designer & Preview Tool
Plan and preview your Instagram grid layout before posting. Drag & drop images, rearrange your feed, and export a visual mockup of your profile grid.
Drag & drop images onto cells, or click Upload Images to fill the grid. Reorder by dragging between cells.
About
An inconsistent Instagram grid costs engagement. Studies show profile visitors decide within 3 - 5 seconds whether to follow. That decision is driven almost entirely by the visual coherence of your top 9 - 12 posts. Posting without previewing the grid is equivalent to publishing a magazine without a layout proof. This tool renders your planned posts into a pixel-accurate 3-column grid matching Instagram's native profile view. You upload images locally (nothing leaves your browser), drag them into position, and evaluate color flow, visual weight distribution, and thematic rhythm before committing a single post.
The preview uses a center-crop algorithm that replicates Instagram's default square thumbnail behavior: each image is reduced to a 1:1 aspect ratio by extracting the largest centered square from the source, exactly as the platform does. Grid dimensions are adjustable from 3×3 up to 3×9 rows for long-range feed planning. Limitation: this tool approximates thumbnail rendering. Instagram may apply slight reframing on non-square originals depending on device pixel ratio. Pro tip: plan in batches of 3 to maintain row-level coherence, which is the atomic visual unit of the Instagram grid.
Formulas
The center-crop algorithm extracts the largest square from a source image of width W and height H:
s = min(W, H)
Crop origin coordinates:
x0 = W − s2 y0 = H − s2
The canvas drawImage call uses parameters (x0, y0, s, s) to extract the region, then scales it to the cell display size d × d pixels.
Grid cell index mapping from 2D position to 1D array:
index = row × cols + col
Where cols = 3 (fixed, matching Instagram), row ∈ [0, R − 1], col ∈ [0, 2].
Average color per cell for harmony analysis is computed by sampling every kth pixel:
= 1N N∑i=1 pi
Where pi is the RGB value of the ith sampled pixel, and N is total sampled pixel count. This yields per-cell dominant color for visual coherence assessment.
