There is no confirmed compatibility. Samsung’s official materials reviewed as of October 3, 2026, list accessories for the Galaxy S26 series but do not establish that an S26 Ultra case or screen protector will fit the Galaxy S27 Ultra. Until Samsung or an accessory maker confirms a specific product works with the S27 Ultra, treat protection as model-specific.
What Samsung’s specifications establish
Samsung gives the Galaxy S26 Ultra dimensions as 78.1 × 163.6 × 7.9 mm and its display size as 6.9 inches, measured diagonally across the full rectangle. Those figures describe the S26 Ultra only; they do not establish the S27 Ultra’s dimensions or accessory fit. Samsung’s S26 announcement provides the S26 Ultra specifications.

Samsung’s accessories page lists cases and screen film for the Galaxy S26 series and notes, “Available cases vary by model.” That supports checking the exact model named on an accessory listing, not assuming compatibility across generations. See Samsung’s mobile accessories listings.

Why a close-looking phone may still need different accessories
A case depends on more than overall height and width: its edges and openings need to align with the phone’s shape and components. A screen protector also needs to match the display’s coverage and edges, and may need to work with functions such as the fingerprint reader. Samsung’s accessory reference resource explains that its drawings show device shape and major component placement for accessory manufacturers. Its displayed 2026 reference is for the Galaxy S26 series; it does not list a Galaxy S27 series reference. Samsung Developer accessory reference resources.

What to do before reusing or buying protection
- If you are buying now: choose a case or screen protector explicitly listed for your exact phone model. Do not rely on a listing that names only “Galaxy Ultra” or another generation.
- If you already own an S26 Ultra accessory: check its manufacturer’s compatibility list or contact the maker for an explicit S27 Ultra confirmation before installing it.
- When a maker claims cross-generation fit: check that the case openings align, the screen protector covers the intended display area, and any stated fingerprint or display functions remain compatible. Also check whether the case and protector are designed to be used together.
- Before purchasing or fitting: recheck Samsung’s specifications and the accessory maker’s exact model listing. Compatibility information may change when official S27 Ultra information and products become available.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
