Watch Band Sizing Help

Not sure what size watch band you need? Here are some tips to help you.
(sizes are in metric measurements, conversion chart available below) 

    Lug Width x Buckle Width
    - Watch bands typically taper a bit so that the underneath of the watch strap is not as wide as where it attaches to the watch. We list our products with both the lug width and buckle width in case you would like to match your strap with an original buckle or clasp. See below for lug width sizing.

    If you are using a buckle or clasp supplied by us, we ensure the correct size and attach your selection to the strap before shipping; just select the lug width you need for your watch and we'll do the rest.

    Watch Band Lengths on our site are designated as follows:

    Short               6-1/2" - 6-3/4", for wrist sizes under 6-1/2"
    Medium:          7" - 7-1/4", for wrist sizes up to 6-3/4" - standard ladies length
    Regular:          7-1/2", for wrist sizes up to 7" - classic men's length
    Long:               8", for wrist sizes up to 7-3/4" - standard men's length
    XL:                  8-1/4" - 8-5/8" - for wrist sizes over 7-3/4"

    Exact lengths for each product are noted in the description field.


    Lug Width Sizing:


    Your existing band may have the width already imprinted on the back. For example, the number "20" means it is a 20mm wide strap and that is the size you will need to replace your band.



    You can also measure the inside dimensions of your watch lugs with a ruler or measuring calipers to determine the size you need. 

    Buckle Width Sizing:
    Measure the inside width of the buckle for the correct buckle measurement.

    If you don't have a way to measure, you can use our Printable Measuring Guide to measure your lug width or existing strap.

    What Length do I need?

    Our straps accommodate most wrist sizes. We offer Short/Medium, Regular/Long and XL lengths.

    Regular/Long length watch straps are between 7-1/2" and 8" in total length. This is a standard men's length for wrist sizes 6-3/4" to 7-1/2". Hirsch brand straps in this option are all 120x80mm - 7-7/8", labeled "L" on tags. Lengths are noted in the product details.

    Short/Medium length watch straps are approximately 7" total length. Hirsch brand straps in this option are 110x70mm - 7-1/8", labeled "M" on tags; perfect for ladies length. See "Search By Size" Menu for lug width options in these lengths. For wrist sizes under 6-3/4"

    XL length watch straps are between 8-1/8" and 8-5/8" in total length, best for wrist sizes over 7-1/2". Hirsch brand straps in this option are 120x100mm - 8-5/8". See "Search By Size" Menu for lug width options in these lengths.

    Shorter and longer lengths in certain styles may be available - custom straps also offered - contact us with any special requests.

    Lengths are measured by adding the length of each side of the strap from end to end not counting the buckle/clasp or the watch itself. Measure your existing band like this to determine the length you need.


    120mm + 80mm = 200mm total length.
    This is a 7-7/8" Men's Regular/Long Length band.


    If you do not currently have a band in the correct size, you can measure your wrist instead. As a general rule, your watch band length should be approximately 1" longer than your wrist size.
    *This is only an approximate suggestion. Watch size, strap thickness and personal wearing preference can vary the length needed.
