Panorama Overlap Calculator

Frequently Asked Questions

How much overlap do I really need?

For most lenses 25-35% overlap is sufficient. At the wide end (below 24 mm) or with highly repetitive textures (clear sky, water), increase to 40-50% so the stitcher finds enough matching features.

What is the no-parallax point?

The point inside the lens where light rays converge before hitting the sensor. Rotating around it eliminates parallax shift between foreground and background elements. It is different from the physical center of the lens barrel.

Does this work for fisheye lenses?

No - fisheye lenses use equidistant projection, not rectilinear, so the arctan formula over- or under-estimates the true FOV. You need fisheye-specific stitching software and a different planning approach.

Can I shoot a panorama handheld?

Yes for simple landscapes without close foreground elements. For architecture, interiors with near objects, or any precise work, a dedicated panoramic head eliminates parallax errors that are impossible to correct in post.

How It Works

A stitched panorama is assembled by overlapping multiple frames. The horizontal field of view of each frame is: FOV = 2 x arctan(sensor_width / (2 x focal_length)). The overlap fraction (e.g., 30%) is the portion of one frame shared with the next; the effective angle each frame advances is FOV x (1 - overlap).

The number of shots needed to cover the desired total angle is: shots = ceil((total_coverage - FOV x overlap) / effective_angle). For a full 360-degree panorama the rotation step between frames is 360 / shots. For a partial sweep, the step is (total_coverage - FOV) / (shots - 1) to correctly distribute the frames across the arc.

Portrait orientation (camera turned vertical) uses the shorter sensor dimension across the panorama sweep, which reduces the per-frame FOV but increases vertical coverage and total resolution - the standard technique for tall scenes.

Use Cases

Panorama planning matters for any multi-frame stitched composition:

Landscape panoramas: planning a 180-degree mountain vista before setting up the tripod

Real-estate and architecture: full 360-degree interior panoramas for virtual tours

Aerial photography: planning drone panoramic sweeps with consistent overlap for clean stitching

Astro-panoramas: tiling the Milky Way across multiple wide-angle frames

Portrait-orientation tall panoramas: capturing a full waterfall or skyscraper in a single composite

Tips

Keep overlap at 30-40% for wide-angle lenses with significant edge distortion - stitching software needs those extra shared pixels to find control points.

Rotate around the lens entrance pupil (no-parallax point), not the tripod screw, to avoid near-far alignment errors when the scene has a close foreground.

Lock manual exposure, white balance, and focus before the sweep so all frames blend seamlessly - even a one-stop EV shift between frames creates visible seams.

Shoot a few extra frames at the ends of the sweep and add extra degrees to the coverage value to budget for the rectangular crop that removes curved edges after stitching.

For very wide lenses (below 24 mm on full-frame), enable lens correction in your stitching software before assembling the panorama to reduce barrel distortion artifacts at the seams.
