How to Build Seamless Instagram Carousels Without Pixel Gaps
Creating a seamless Instagram carousel requires a master canvas width that is an exact multiple of the slide width, e.g., 3240×1350 px for 3 slides. Common failures include resizing to non-divisible widths, placing content on cut boundaries, and inconsistent compression. A reliable workflow involves designing on a single master canvas, exporting once, and splitting deterministically to avoid one-pixel gaps.
