Size Guide
Port Royal Supply Co. Size Guide
Finding the right fit should feel easy. Our size guide is here to help you choose the best size across Port Royal Supply styles, from everyday tees to performance shirts and boardshorts. Measurements are approximate and may vary slightly by style.shopify+1
We recommend comparing the measurements below to a shirt or pair of shorts you already own and love. Lay the garment flat, measure it, and match it to the closest size for the most accurate fit.
How to measure
Tops
-
Chest width: Measure straight across the chest, 1 inch below the armhole, from side to side.
-
Body length: Measure from the highest point of the shoulder down to the bottom hem.
-
Sleeve length: Measure from the shoulder seam to the sleeve opening, if applicable.
Boardshorts
-
Waist: Measure across the waistband while laid flat, then double it for full waist measurement.
-
Outseam: Measure from the top of the waistband to the bottom hem on the outer leg.
-
Inseam: Measure from the crotch seam to the bottom hem.
Tees and long sleeves
Our standard tees and long sleeves are designed for an easy, everyday fit. If you are between sizes and prefer a more relaxed feel, we recommend sizing up.
Fit note: True to size with a comfortable, casual fit made for everyday wear on and off the water.
Performance shirts
Our performance shirts are built for movement, sun coverage, and long days outside. Depending on the fabric blend and intended use, performance styles may feel slightly more athletic through the shoulders and chest than a standard cotton tee, so refer to the individual product description for style-specific fit notes.
Fit note: Designed for active use. If you like a looser fit for fishing, boating, or all-day sun coverage, consider sizing up.
Boardshorts
Our boardshorts are sized by waist and built for comfort in and around the water. If you are between sizes, choose based on how you prefer your waistband to sit, especially for non-stretch waist styles.
Fit note: Built for a clean surf fit. Check each product page for stretch, waistband construction, and outseam details.
