How to use this calculator
- Enter the active sensor size, uncropped image size, and actual focal length.
- Choose the camera orientation you will use on the panoramic head.
- Set the horizontal and vertical scene coverage you need.
- Enter the minimum overlap and any click-stop increment from the head.
- Add bracket count, file size, and capture time to estimate storage and duration.
How the shot plan is calculated
The calculator first turns the lens and oriented sensor into rectilinear field of view. In landscape orientation, the horizontal sensor dimension is the sensor width and the vertical dimension is the sensor height. In portrait orientation, those dimensions swap, and the image pixel dimensions swap with them.
The angle of view for one direction is:
A = 2 * atan(S / (2 * f)) * 180 / pi
- S is the oriented sensor dimension in millimeters.
- f is the actual focal length in millimeters.
- A is the single-frame angle of view in degrees.
For a requested overlap o, the largest ideal step is s0 = A * (1 - o). If you enter a panoramic-head click increment, the calculator reduces that ideal step to the largest safe multiple of the detent. For a 360-degree sweep, it also checks whether the detent step divides exactly into a full circle so the last frame closes cleanly against the first. If no safe click-stop pattern exists, the result shows a free-rotation step and names the limitation in the notes.
For an open sweep, the count is one frame when the requested coverage fits inside a single frame. Otherwise the count is:
n = ceil((T - A) / s) + 1
T is the requested coverage and s is the selected rotation step. The same calculation is applied horizontally for shots per row and vertically for the number of rows. Total camera positions are columns * rows, and total source captures are positions * exposures per position.
What changes the result most
Focal length and orientation drive the number of positions. A longer lens narrows the field of view, so it needs smaller rotation steps and more frames. Portrait orientation often raises the number of shots per row, but it gives more vertical pixels and may reduce the number of rows needed.
Overlap and click stops also matter. A higher overlap reduces the step size. A coarse detent can force a smaller step than the arithmetic minimum, increasing the frame count, or it can be too coarse to preserve the requested overlap at all.
What this calculator leaves out
The stitched pixel size is a pre-crop estimate: oriented source pixels plus the non-overlapping contribution of each additional column and row. It does not model projection choice, horizon leveling, warping, blending, missing corners, or edge cropping. Fisheye lenses and strongly distorted ultra-wide lenses do not follow the rectilinear equation well. Coverage near 180 degrees vertically may need separate zenith and nadir frames rather than a simple rectangular grid.
Worked example
Suppose a full-frame camera records 6000 x 4000 px files, uses a 50 mm lens, and is turned to portrait orientation. The oriented frame is 24 mm wide by 36 mm high, so one frame covers 26.99 degrees horizontally and 39.60 degrees vertically.
With 30% overlap and no click-stop constraint, the yaw step is 26.99 * 0.70 = 18.89 degrees and the pitch step is 39.60 * 0.70 = 27.72 degrees. A 120-degree by 60-degree panorama needs ceil((120 - 26.99) / 18.89) + 1 = 6 shots per row and ceil((60 - 39.60) / 27.72) + 1 = 2 rows, for 12 camera positions.
With one exposure per position, 35 MB files, and 3 seconds per exposure, the source set is 12 captures, about 0.42 GB, and 0.60 minutes of capture time. The pre-crop stitched estimate is about 18000 x 10200 px, or 183.6 megapixels.
Common questions
How much overlap should panorama photos have?
Many panoramic workflows use about 25% to 35% overlap for normal rectilinear lenses, and more when the scene has low detail or the lens has visible distortion. The calculator treats your overlap as a minimum, so click-stop rounding may increase the actual overlap.
Should I shoot a panorama in portrait or landscape orientation?
Portrait orientation usually gives more vertical pixels and more vertical field for a horizontal panorama, but it often requires more shots across. Landscape orientation can reduce the number of columns when vertical coverage is modest. The better choice depends on whether final height or capture speed matters more.
How many shots are needed for a 180-degree or 360-degree panorama?
The count depends on focal length, sensor size, orientation, and overlap. A 360-degree panorama is treated as a closed loop, so the calculator chooses a step that covers the full circle and still overlaps back to the first frame.
How do panoramic-head click stops affect overlap?
Click stops restrict the rotation to fixed increments. If the ideal safe step is 18.9 degrees and the head clicks every 5 degrees, the calculator uses 15 degrees because 20 degrees would reduce overlap below the requested minimum.
Do HDR brackets multiply panorama storage and shooting time?
Yes. Brackets are captured at every camera position, so three exposures per position triples the number of source files. The storage and time estimates multiply the grid positions by the exposure count before applying file size and capture time.
