For Anamorphic Desqueeze, keep sensor format, units, focus state, and reference planes attached to the entries.
The lens or focus result will appear here with supporting checks.
Keep projection in view for Anamorphic Desqueeze
Apply squeeze factor to width and aspect ratio.
Anamorphic Desqueeze Calculator reports desqueezed frame from Recorded width, Recorded height, Squeeze factor. Calculate desqueezed width and aspect ratio.
Rectilinear, fisheye, anamorphic, and shifted images map angles differently.
Inputs that define desqueezed frame
Record Recorded width and Squeeze factor from one camera, lens, focus setting, and frame. Preserve the unit printed beside Recorded width and Squeeze factor; converting one without the other changes the geometry behind desqueezed frame.
Identify whether Recorded width came from EXIF, the lens scale, a test frame, a sensor specification, or direct measurement before comparing another Anamorphic Desqueeze setup.
The calculation behind Anamorphic Desqueeze
Apply squeeze factor to width and aspect ratio.
For Anamorphic Desqueeze, the page keeps the intermediate geometry visible and rounds only the displayed desqueezed frame. Verify the center and edge behavior separately when the model is projection-sensitive.
Worked check with the published values
For Anamorphic Desqueeze, calculate the defaults and save the displayed desqueezed frame with its supporting quantities. Change only Recorded width in the Anamorphic Desqueeze example, predict the direction of desqueezed frame, and calculate again.
Restore Recorded width and confirm the first result returns. That reset test distinguishes a real change in desqueezed frame from a stale Recorded width value or an unnoticed unit conversion.
Where the desqueezed frame model stops
Cropping, pixel aspect ratio, and delivery framing may change the final display dimensions.
Desqueezed frame cannot judge the lens rendering, autofocus repeatability, decentering, field curvature, contrast, stabilization, or the success of the intended composition.
Measurement boundary for Anamorphic Desqueeze
Define the reference plane for Recorded width and what is included in Squeeze factor. For Anamorphic Desqueeze, a distance referenced to the sensor cannot silently replace one measured from the lens front, mount, principal plane, or subject surface.
For Anamorphic Desqueeze, list any crop, correction profile, teleconverter, extension, close-up element, breathing, or shift already represented by Squeeze factor. Apply each Anamorphic Desqueeze adjustment once—either inside the entered measurement or explicitly afterward, never in both places.
Reading the result in practice
Compare desqueezed frame with a test frame, focus chart, measured field width, sensor specification, or known limiting case. If that check disagrees with desqueezed frame, inspect the units and the reference plane used for Recorded width before changing the formula.
The Lens Compatibility Image Circle Calculator addresses a nearby lens question, but its output should be transferred only when the format and geometry remain the same.
A second comparison for Anamorphic Desqueeze
Use Depth of Field Comparison Calculator for the next defined quantity. Even if it also reports millimeters, meters, degrees, or pixels, its assumptions are not interchangeable with Anamorphic Desqueeze.
Label the alternative setup and change one variable so the difference in desqueezed frame remains explainable.
Precision and available settings
Keep full precision while desqueezed frame feeds another calculation, then round to the precision supported by the lens scale, rail, sensor specification, or field measurement.
Extra decimals in desqueezed frame cannot repair uncertainty in Recorded width, Squeeze factor, pupil location, focus breathing, or the selected sharpness criterion.
Saving a reproducible lens record
Save Recorded width, Recorded height, Squeeze factor, desqueezed frame, camera format, lens state, focus distance, and date. Mark nominal specifications separately from measured values.
For Anamorphic Desqueeze, when the lens, format, crop, focus, or camera position changes, preserve the earlier Anamorphic Desqueeze case and calculate a labeled replacement.
Designing a useful test for Anamorphic Desqueeze
For Anamorphic Desqueeze, choose a subject with measurable edges or planes and keep the camera position fixed unless distance is the quantity under test. Record Recorded width before the first frame and confirm Squeeze factor from the same lens state. For Anamorphic Desqueeze, note the marked focal length and focus state beside Recorded width; internal focusing or zoom position can change the effective geometry.
After the published Anamorphic Desqueeze baseline, create a second case that changes only Squeeze factor by a measurable amount. A doubled distance, one-stop aperture change, known crop, measured rail movement, or fixed pixel dimension gives desqueezed frame an independent directional expectation.
For Anamorphic Desqueeze, inspect both center and edge when using desqueezed frame; projection, coverage, vignetting, distortion, diffraction, or field curvature may vary across the image. A center-frame Anamorphic Desqueeze measurement may agree while the edge departs because of behavior outside this simplified equation.
Using desqueezed frame in a shooting decision
For Anamorphic Desqueeze, translate the number into one concrete choice: move the camera, change focal length, select an aperture, set a rail position, confirm image-circle coverage, or decide whether the subject will occupy enough pixels. Keep that action beside the saved desqueezed frame so another person knows why the calculation was made.
If desqueezed frame falls between marked Anamorphic Desqueeze controls, retain the unrounded value and document the setting actually used. Test the neighboring available Squeeze factor value instead of claiming more adjustment precision than the lens, rail, focus scale, tilt mechanism, or camera position provides.
For Anamorphic Desqueeze, after the photograph, compare the recorded frame with the expected desqueezed frame. Save deviations that repeat across tests; they can reveal focus breathing, a nominal sensor dimension, an entrance-pupil offset, a lens-specific projection, or another stable correction worth applying in future Anamorphic Desqueeze work.
Questions about anamorphic desqueeze calculator
What does Anamorphic Desqueeze Calculator calculate?
It calculates desqueezed frame from Recorded width, Recorded height, Squeeze factor. Apply squeeze factor to width and aspect ratio.
Which measurement should I verify first?
Confirm Recorded width, its unit, and its reference plane before using the other entries.

Cropping, pixel aspect ratio, and delivery framing may change the final display dimensions.
How can I check desqueezed frame?
Run the defaults, change only Squeeze factor, predict the direction, and restore the starting value.
