Case sizes, shelf space and disc compatibility

Use the measurements below as starting points, then measure your own cases and shelf. Packaging varies by product, country, slipcover and set.

Case dimensions at a glance

Cases stand upright with their spines facing out. The spine thickness consumes the shelf run; the case face width is the shelf depth, and case height is the vertical clearance. These are individual published examples, not universal format standards.

Nominal package dimensions; width × height × spine thickness
Case example	Face width	Height	Spine thickness used	Evidence and limitation
DVD keep case	135 mm	190 mm	15 mm starting estimate	Keep case overview; thickness varies, especially multi-disc and slim cases. Measure the case you own.
Blu-ray case (reseller listing)	135 mm	171.5 mm	13 mm	CDROM2GO dimensions; one packaging listing, not a format-wide standard.
Slim Blu-ray case (reseller listing)	135 mm	171.5 mm	7.5 mm	CDROM2GO dimensions; slim products vary.
4K UHD case example	136 mm cover width	171.5 mm	11 mm	Duplication.com packaging listing; a reseller example, not every 4K package.
Blu-ray SteelBook example	136 mm	171.4 mm	15 mm	Scanavo finished-size specification (PDF); one manufacturer's specified product, not all SteelBooks or Blu-ray packaging.

The cited Blu-ray reseller example is 13 mm; the cited SteelBook specification is 15 mm. Do not collapse those different examples into one “standard Blu-ray” measurement. Slipcovers, box sets, multi-disc cases and regional packages need their own measurement.

Estimate shelf capacity

Enter the usable horizontal run of each shelf, measured inside the supports. The calculator packs the thickest cases first and reports the actual per-shelf counts. Its first-fit allocation is a practical estimate, not a guaranteed optimal packing solution.

The calculator needs JavaScript. The dimension table above remains available; as a quick single-format estimate, divide usable shelf run in millimetres by the measured spine thickness and round down.

Formula: for one format, the per-shelf limit is floor(usable run ÷ spine thickness). For a mixed shelf, each case occupies its own thickness; the tool places whole cases and never converts face width or height into shelf run.

Check disc, player and display compatibility

A disc must first be readable by the player. Region and video output are separate checks: a region mismatch can stop playback, while a lower-resolution or non-HDR display can still show a supported disc at reduced output. Select only capabilities confirmed in the exact player manual and disc packaging.

Manual compatibility check (JavaScript is off)

The interactive checker needs JavaScript. You can still compare the actual package and manual:

Confirm that the exact player manual lists the disc format. Do not infer support from the product family name.
Read the region marking on this disc and compare it with the player's documented region. If either is missing, treat region compatibility as unknown.
Compare the player’s documented maximum output with the display’s native resolution. The lower supported resolution limits the picture; neither establishes the disc’s mastering quality.
Check the exact HDR format named on the disc against formats supported by the display. A general HDR label is not proof that the formats match.

If a manual or package does not say, keep that capability unknown rather than guessing.

For source checks, consult the official Sony UBP-X700 manuals page or the manual for your exact player model. A manual for one model cannot establish another model’s supported discs, region behaviour, output resolution or HDR formats. If a specification is absent or ambiguous, treat it as unknown.

Sources, method and limits

Dimensions are copied from the individually linked packaging references above and the retained research record checked September 27, 2026. Case sizes are nominal examples, not manufacturing tolerances or format guarantees. Measure thick collections, slipcovers and box sets directly.

The shelf planner’s buffer is reserved empty space, applied to usable run before packing. For mixed formats, it sorts cases by entered thickness and places whole cases into each shelf run. Its shelf count is a best-fit-first estimate; unusual shelf obstructions, dividers, bowing, clearance needs and odd-shaped sets are outside the model.

The compatibility check keeps three questions apart: can the player read this disc format; do disc and player regions match when region coding applies; and what picture can the player/display combination output? HDR is assessed separately from resolution. It does not assume every 4K disc is region-free, every Blu-ray player reads every DVD, or that a display’s HDR label covers every HDR format.

Identify the film before measuring its edition

A collection can mix single films, anniversary packages and multi-film boxes. The film collector reference list helps you identify the title first, then check the actual disc and case. These guides give a starting point for the titles they cover:

Use the measurements of the package you own in the tools above. A film title alone cannot establish the thickness of its case or the number of discs inside.
