Gigapixel Stitch Frame Count Calculator
A gigapixel panorama is built by shooting a grid of overlapping frames and stitching them together. The number of frames depends on how wide and tall the scene is, the field of view of a single frame, and how much you overlap neighbours so the software can blend them. This calculator returns the columns, rows, total frames, and the raw captured gigapixels from the panorama angles, the per-frame field of view, the overlap, and the megapixels per frame. Use it to plan a shoot and to estimate storage and stitching time.
Stitch frame count formula
Effective frame width = frame H FOV * (1 - overlap/100)
Columns = ceil(pano width / effective frame width)
Rows = ceil(pano height / (frame V FOV * (1 - overlap/100)))
Total frames = columns * rows
Captured gigapixels = total frames * megapixels per frame / 1000
Overlap shrinks the usable field of each frame, so more frames are needed. Each axis rounds up to a whole frame.
Panorama planning context
- 20 to 30 percent overlap is typical for reliable stitching.
- Longer lenses see a narrower field, so they need far more frames.
- The captured gigapixels exceed the final stitched canvas because overlaps merge.
- Get per-frame field of view from a field-of-view calculator using sensor and focal length.
- Each axis rounds up so the whole scene is covered with edge overlap.
Gigapixel stitch: frequently asked questions
How many frames do I need for a panorama?
Divide the panorama's angular width by the effective horizontal field of view of one frame, where the effective field is the single-frame angle reduced by the overlap. Do the same vertically, round each up, and multiply. Columns equal ceil(pano width / (frame width times (1 minus overlap))), and total frames equal columns times rows.
How much overlap should I use between frames?
Stitching software needs overlap to match neighbouring frames, and 20 to 30 percent is typical. More overlap makes blending easier but needs more frames; less overlap risks stitching failures, especially with wide lenses that distort toward the edges. The overlap fraction is a user input here.
How is the captured gigapixel count estimated?
Multiply the total number of frames by the megapixels per frame to get the raw captured pixel count, then divide by 1,000 for gigapixels. The final stitched image is smaller because overlapping areas merge, so this figure is the data captured, not the final canvas size.
What field of view should I enter per frame?
Use the horizontal and vertical angle of view of your lens on your camera, which you can get from a field-of-view calculator using sensor size and focal length. Longer lenses give a narrower per-frame field, so they need many more frames to cover the same panorama.
Why round the number of frames up?
You cannot shoot a fraction of a frame, and the panorama must be fully covered with overlap at the edges, so each axis rounds up to the next whole frame. Rounding up also leaves a small margin that helps stitching software find matching features at the boundaries.
