Michael Kors Band Size Chart by Model

Michael Kors makes this harder than it should be: the brand sells dozens of collections, the same collection name ships at several widths (Runway alone runs 12 to 24mm), and retailer spec tables disagree with each other on the same watch. The one thing that never lies is the code engraved on the caseback: MK or MKT followed by four digits. Type it below, or scan the table, and you get the band width plus the mount warning that decides whether a generic 20mm strap will actually fit. Every width below is confirmed by the official dealer strap catalog plus at least one independent retailer or the brand's own product page; where honest sources disagree, the row says so instead of averaging.

Quick answers: most women's Michael Kors watches take 14, 16, 18 or 20mm; most men's take 20 or 22mm; the big Runway and Everest chronographs go 24mm; the Dylan is the odd one out with an integrated 28mm strap. The Gen 5 and Gen 6 Access smartwatches take 20mm (Lexington, Darci, MKGO, Sofie) or 22mm (Bradshaw).

Look up your caseback code

Flip the watch over. The four-digit code after MK (analog) or MKT (smartwatch) is the key to the table. An AMK prefix means you are reading the strap's own SKU, not the watch: those codes also work in the table because the strap SKU embeds the watch code, but the engraved watch code is the safer key [1]. If the code is not in the table, do not guess from the collection name; measure the gap between the lugs with a ruler (the measuring guide shows how) or check the guidance block at the bottom [3].

The chart: 108 verified models

Sorted by width, then code. The mount column is the one to read before ordering: No means the watch has an integrated or curved-end fitting and a generic straight strap will not seat against the case.

Why the mount column matters more than the width

A width number is only half the answer on a Michael Kors. Three attachment styles exist across the range [4]: straight-end straps that any generic band of the right width will replace, curved-end straps that need the OEM silhouette to hug the case, and full integrated fittings where the band is part of the design and nothing generic works at all. The flagged rows are the ones where the official dealer strap pages say straight strap mount: No: the MK6650 Channing bracelet, the MK8184 Dylan (28mm strap narrowing to 13mm at the caseback), the MK6200 Audrina resin bracelet, the MKT5136 and MKT5135 Gen 6 Bradshaw smartwatches, and several Gen 5 Access models with screw or quick-release fittings. If your watch is in that group, order the original strap by code or a code-specific curved replacement, not a universal band.

Access smartwatch rows and the charger question

The MKT rows are Michael Kors Access smartwatches. Band widths behave like the analog line (20mm on the 43mm MKGO, Darci, Sofie and Lexington cases; 22mm on the 44mm Bradshaw cases; 24mm on the Grayson), but chargers do not: generation decides the charger, not width. The heart-rate models take the 5-dot magnetic charger, and the official charger manual lists exactly which MKT codes belong to that family; the non-HR Gen 3 Sofie (MKT5022) and the non-HR Runway (MKT5054) are explicitly excluded from it [5]. Counting the contact dots on the back of the watch is the fastest check before ordering a spare charger. The Fossil smartwatch band chart covers the sibling platform; Michael Kors watch licensing sits inside the Fossil Group, so accessory rails are shared.

Where sources disagree, and the rows we refused to publish

Width conflicts on Michael Kors watches are common and rarely random: one retailer measures the caseback taper instead of the lug width, another copies a wrong cell from a shared feed. Three honest disagreements are disclosed rather than averaged. The MKT5134 Gen 6 Bradshaw: the OEM bracelet page and two dealers say 22mm, one retailer table says 20mm on the same EAN; we publish 22mm with the majority and say so in the row. The MK2740 and MK5353 were flagged as conflicts and then resolved: a dealer catalog had the two widths swapped relative to every strap-surface source, and the official dealer strap pages plus two independent retailers each settled them at 18 and 20mm respectively. And three candidate rows are deliberately absent because no second independent source exists: the MK3260 Camille Petite (the only agreeing second source is a retailer with a documented error record), the MK5899 Lindley (official-dealer family only, two rescue passes failed to find an independent), and the MK5688 Parker, where published figures spread across 19, 20 and 12mm depending on which part of the watch each seller measured. If you own one of those three, measure between the lugs before ordering; do not trust any single retailer table for them.

Your code is not in the table

Then the honest answer is the measuring one, and this site will not invent a width. Pop the spring bar or measure between the lugs where the strap meets the case, in millimeters: the how to measure guide covers the technique, the lug width chart explains what the number means across brands, and the spring bar size table covers the pin you will be handling while you are in there. Two naming traps worth knowing before you search elsewhere: some codes carry two collection names depending on the seller (the MK5038 is sold as Ritz Tortoise by retailers and titled Bryant on the OEM strap; the MK6992 is Lennox at independents and Camille on the strap page), and a 16, 17 or 19mm reading on a bracelet watch is usually the clasp or caseback taper, not the lug width.

Related guides

Once you have the width: the band size chart sets Michael Kors widths in context across brands, the watch database lists cases by wrist fit, the band adjustment guide handles link removal on the bracelet models, and the mesh band guide covers the Maisie-style sliding clasp. For sibling brand charts: Fossil (Michael Kors watches are Fossil Group licensed, shared accessory rails), Bulova, Seiko, Citizen, Timex and Invicta.
