      Size Guide

      Size Guide

      The complete fit handbook for Gridiron Kit jerseys — measured to the inch and the centimeter so you order the right size with total confidence.

      Quick rule: Not sure between two sizes? For a game-day, loose fit size up. Every jersey is covered by our 30-day return policy if the fit isn't right.

      1 · How To Measure

      Wear minimal clothing and stand relaxed. Use a soft (cloth) tape measure, keep it level and snug but not tight. All our size charts use body measurements, not garment measurements — so measure your body, not a shirt you own.

      Chest widest part, arms down Body Length shoulder → hem Waist natural waist / navel Hips widest seat Inseam crotch → ankle Sleeve shoulder → cuff
      1

      Chest

      Wrap the tape around the fullest part of your chest, arms relaxed at your sides. Keep it level across the back.

      2

      Waist

      Measure at your natural waistline, roughly level with your navel. Don't suck in.

      3

      Body Length

      From the highest point of the shoulder (near the neck) straight down to the hem.

      4

      Sleeve

      From the shoulder seam out to the cuff — most relevant for jerseys.

      5

      Hips

      Around the widest part of your hips/seat, feet together. Useful if layering bottoms under pads.

      6

      Inseam

      From the crotch seam down the inner leg to the ankle. Reference for padded-game layering.

      Units: 1 inch = 2.54 cm. Our charts show both — inches first, centimeters in small gray text. When between numbers on the chart, round up to the larger size for a comfortable fit.

      2 · Men's Jerseys

      Body measurements in inches (and cm). "Fit" describes how the cut sits relative to your body.

      Pro tip: our men's jerseys are cut to layer over shoulder pads, so they run slightly roomy. For an off-field, body-skimming fit, consider sizing down one.

      3 · Women's Jerseys

      Tailored through the torso with a slightly tapered waist. Measurements in inches (and cm).

      SizeBustWaistHipsBody Length
      S38"97 cm32"81 cm40"102 cm27"69 cm

      2XL50"127 cm44"112 cm52"132 cm31"79 cm

      Women's jerseys run true to the chart. If you're between sizes and prefer a relaxed game-day look, size up; for a fitted look, stay true.

      4 · Youth Jerseys

      Chest measurement with recommended height and age range. Measurements in inches (and cm).

      SizeChestApprox. HeightApprox. Age

      YXL41"104 cm60–64"152–163 cm14–16
      Tip for growing kids: If your child is between sizes or near the top of a range, size up — jerseys layer easily and they'll get another season of wear. A YXL often bridges nicely into adult Small.

      5 · Height & Weight Fit Finder

      The fastest way to pick a size if you don't have a tape measure. These are starting points — athletic/wide builds should size up.

      Men

      5'9"+180–200 lb2XL

      Weight is only a guide — a 185 lb powerlifter and a 185 lb runner need different sizes. Always trust your chest measurement over the scale.

      6 · Big & Tall Jerseys

      For broader builds and longer torsos. "Tall" adds ~2" to body length and ~1.5" to sleeves; Big adds chest/waist room.

      8 · Authentic vs. Replica — Which Fit?

      Authentic (Game Fit)

      Cut to layer over pads, like the pros wear on the field.

      • Slightly loose through the body and sleeves
      • Longer sleeves for pad coverage
      • Stitched, durable numbers & names
      • Best for: game day, layering, true fan look
      • Size down if you want a snug, off-field fit

      Replica / Throwback (Tailored)

      Everyday fan wear, closer to the body.

      • More tailored through the torso
      • Shorter, lighter sleeves
      • Applied numbers suited to casual wear
      • Best for: casual wear, gifting, youth
      • True to the chart — order your normal size
      Custom name & number jerseys are made to order in your selected size. Authentic custom runs about one size larger in feel than Replica custom. Double-check the measurements before ordering — personalized items follow the standard return rules only if defective.

      9 · Between Sizes? Decide Here

      Use your build and how you'll wear it to break the tie.

      Athletic / broad shoulders

      Chest is the priority. Size up so the chest isn't tight; the waist will be a touch loose but looks intentional.

      Slim build

      Stay true to the chart, or size down one for a sharper silhouette (Replica especially).

      Wearing pads / layers

      Size up at least one from your tee size — Authentic jerseys are already cut for this.

      Gift, unknown size

      Pick the recipient's usual tee size; our 30-day return covers exchanges if needed.

      Long torso

      Go Tall (LT/XLT/2XLT) or simply size up — body length grows with the size.

      Prefer loose / oversized

      Size up one to two for the relaxed streetwear look.

      10 · Jersey Fabric & Feel

      • Authentic Game Jerseys: 100% polyester breathable mesh — wicks sweat, holds its shape, lightweight for all-season wear on the field or in the stands.
      • Replica / Throwback Jerseys: lighter poly-blend performance knit with a softer hand — built for everyday fan wear and all-day comfort.
      • Custom Name & Number Jerseys: made on the same Authentic or Replica body you choose; numbers are stitched (Authentic) or applied (Replica) for lasting wear.

      11 · Jersey Care

      • Turn the jersey inside out before washing.
      • Machine wash cold on a gentle cycle; mild detergent only.
      • Hang dry — avoid tumble dryers and direct high heat.
      • Do not bleach, iron directly on numbers, or dry-clean.
      • Store flat or on a wide hanger to preserve shoulder shape.

      Following these steps keeps stitched numbers and prints intact season after season — and protects your 365-day warranty coverage.

      12 · Fit FAQ

      Do your jerseys run true to size?

      Replica jerseys run true to the size chart. Authentic jerseys are cut roomier to fit over pads, so they feel about one size larger than a standard shirt — size down if you want a fitted look.

      Will the jersey shrink after washing?

      Our polyester mesh and knit fabrics are pre-shrunk and resist shrinkage. Following the cold-wash, hang-dry care instructions, you should see no noticeable shrinkage.

      I'm between two sizes — which should I pick?

      For a relaxed game-day fit, size up. For a tailored everyday look, size down (Replica) or stay true (Authentic). See section 9 for build-specific guidance.

      Can I wear shoulder pads under a Replica jersey?

      You can, but it'll be snug. Authentic jerseys are designed for pads; for padded wear we recommend Authentic or sizing up in Replica.

      What if the size I ordered doesn't fit?

      Unworn jerseys with tags can be returned within 30 days for an exchange or refund. See our Return Policy. Custom name/number jerseys are returnable only if defective.

      Do women's jerseys run small?

      No — they follow the women's chart in section 3 and run true. If you're between sizes and want a looser fit, size up; for a fitted look, stay true.

      How do I get a longer length if I'm tall?

      Choose our Tall sizes (LT, XLT, 2XLT) which add about 2" of body length and 1.5" of sleeve, or simply size up.

      NFL Football Fan Jersey

      San Francisco 49ers 80th Anniversary Custom Game Jersey - White

      Game | Custom Option | White

      There is a particular kind of pride in wearing San Francisco 49ers colours somewhere far from home. This jersey carries it well.

      The San Francisco 49ers Game Jersey in White is a fan game built for people who actually watch the games. It keeps the on-field look fans know - team colourway, clean lettering, familiar number placement - while staying light and easy enough for a full day of wear.

      Which club

      San Francisco 49ers colours are the whole point here, and the white base keeps them sharp whether you are at the ground or on the sofa.

      ClubSan Francisco 49ers (NFL football)
      Gender / fitUnisex (men's and women's)
      VersionGame fan build
      ColourwayWhite
      SizesMultiple sizes available - see the size options on this page

      Listed under Unisex (men's and women's). If you prefer a looser, oversized look, one size up usually gives it without losing the shape.

      Who it is for

      The NFL buyer is usually buying for a reason rather than browsing: Sunday fixtures, a tailgate, a gift for someone who already has three. What settles the choice is whether the shirt looks right on the body and survives regular washing, not a long specification list.

      Details that matter when choosing this San Francisco 49ers jersey

      Start from the San Francisco 49ers Game jersey and the rest of the choice narrows quickly: San Francisco 49ers colours, team styling, and a cut that works with jeans as easily as with shorts.

      Everything starts with the San Francisco 49ers jersey - it sets the colourway, the fit and the look the rest of the range is built around.

      Filed under NFL football jersey, this sits inside the NFL side of the store, so it is filtered and compared against the rest of the NFL range rather than the general football category.

      The 49ers match day jersey buyer is usually buying for a specific occasion rather than browsing, so the useful details here are the fit, the fabric and how the colour looks outside the stadium.

      Ordering the custom San Francisco 49ers jersey is straightforward - the name and number fields appear next to the size selector, and the print is applied per order rather than per batch.

      Print and lettering

      Print quality is the first thing people check, and this holds up close.

      Custom name option

      A custom name turns a San Francisco 49ers jersey into something nobody else has - and it is the detail people notice first.

      Everyday wear

      Easy to wear on an ordinary day - it does not announce itself as sports kit unless you want it to.

      Product details

      Match day ready

      Kickoff, tip-off, first pitch - it does not matter which. This is the shirt that comes out when the San Francisco 49ers play.
