Polo Ralph Lauren Size Guide: Fits, Charts & Tips
You ordered a Polo Ralph Lauren polo shirt online, picked your usual size, and it arrived like a tent. Or you went with Slim Fit and could barely lift your arms. This happens more than you'd think. Ralph Lauren's three fits produce radically different garments from the same letter size. A Medium in Classic Fit and a Medium in Slim Fit can differ by 7–8 cm across the chest.
This guide covers men's, women's, and kids' sizing for Polo Ralph Lauren, built from the brand's official measurement charts and verified against real products on Stylino. Whether you're buying a polo ralph lauren sweater, a polo shirt, or a t-shirt for your kid, getting the fit right the first time saves you a return shipment and a two-week wait.
Understanding Ralph Lauren's 3 Fits
Most brands offer one or two fits. Ralph Lauren offers three, and they feel like separate products.
Classic Fit is the roomiest option. Lower armholes give more range of motion. The sleeve runs fuller, hitting roughly at the elbow. This is the original Ralph Lauren cut from the 1970s, designed for a relaxed drape. It works for standard to larger builds. If you want less volume, size down one.
Custom Slim Fit sits in the middle and works for most people. Higher armholes, a slightly tapered torso, and a sleeve about 3.8 cm shorter than Classic. The official Ralph Lauren fit guide calls this their recommended starting point for first-time buyers. True to size for lean-to-average builds.
Slim Fit is the trimmest cut. Tapered waist, narrow sleeves that hug the bicep. Built for lean frames. If you lift weights or have broader shoulders, size up without hesitation.
Here's what trips people up: all three fits use the same body measurement chart. The difference is in how the garment is cut around those measurements, not in the measurements themselves.
How to Measure Yourself
Five measurements, a flexible tape measure, and two minutes.
Measure your chest
Wrap the tape around the fullest part of your chest, under your arms. Keep it level across your shoulder blades. Snug but not compressed.
Measure your neck
For polos with buttoned collars, wrap the tape around the base of your neck. Leave one finger of space between tape and skin.
Measure your sleeve length
Start at the center back of your neck, run the tape across your shoulder point, and down to your wrist bone. Have someone help if you can.
Measure your waist
Wrap the tape around your natural waistline, usually at navel level. Stand relaxed. Don't suck in.
Compare to the charts below
Match your centimetre measurements to the size chart for your category. If you fall between two sizes, your fit preference decides: go down for Classic Fit (it has room to spare) and up for Slim Fit (it doesn't).
Men's Polo Shirt Size Chart
These are body measurements from the Ralph Lauren EU size support page, not garment measurements. You're measuring yourself and comparing to these numbers.
| Size | Chest (cm) | Waist (cm) | Neck (cm) |
|---|---|---|---|
| S | 89–94 | 74–79 | 37–38 |
| M | 97–102 | 81–86 | 38–39 |
| L | 104–109 | 89–94 | 40–41 |
| XL | 112–117 | 97–102 | 42–43 |
| XXL | 119–124 | 104–109 | 44–45 |
The same body measurements apply regardless of fit. A size L covers a 104–109 cm chest whether you pick Classic, Custom Slim, or Slim. What changes is the garment's cut: Classic adds more ease around the torso, Custom Slim removes some of that ease, and Slim removes nearly all of it.
If your chest measures 105 cm: Classic Fit L will drape with several centimetres of room, Custom Slim L sits close but comfortable, Slim Fit L will be form-fitting.
On Stylino, men's polo shirts account for 44% of all 2,563 Polo Ralph Lauren products. Prices range from €31.50 to €135 depending on retailer and colour.
Women's Sizing
Polo Ralph Lauren women's sizing uses US numerical sizes (0–16) alongside an XS–XL letter system. If you normally shop in European sizes, add roughly 4 to the US number: a US 8 is approximately an EU 38–40.
| US Size | Letter | Bust (cm) | Waist (cm) | Hips (cm) |
|---|---|---|---|---|
| 2 | XS | 82–84 | 62–64 | 89–91 |
| 4 | S | 85–87 | 65–67 | 92–94 |
| 6 | S | 88–90 | 68–70 | 95–97 |
| 8 | M | 91–93 | 71–73 | 98–100 |
| 10 | M | 94–96 | 74–76 | 101–103 |
| 12 | L | 97–99 | 77–79 | 104–106 |
| 14 | L | 100–102 | 80–82 | 107–109 |
| 16 | XL | 103–105 | 83–85 | 110–112 |
From tracking 446 women's products on Stylino, two patterns stand out. Women's polo shirts and tops tend to run slightly smaller than comparable fast-fashion brands. And knitwear (like the cable-knit sweater below at €156 via Rodanos) relaxes about half a size after a few wears, so buying true to size works well.

Kids' Sizing
Ralph Lauren kids' sizes use a US age-based system. The table below maps sizes to approximate heights, which is more reliable than age alone.
| Size | Age (approx.) | Height (cm) |
|---|---|---|
| 2T | 2 | 84–89 |
| 3T | 3 | 92–97 |
| 4T | 4 | 99–104 |
| 5 | 5 | 107–112 |
| 6 | 6 | 114–119 |
| 7 | 7 | 122–127 |
| 8–10 | 8–10 | 130–140 |
| 12–14 | 11–13 | 143–158 |
| 16–20 | 14–16 | 161–175 |
Stylino tracks 205 kids' Polo Ralph Lauren products (94 boys', 111 girls'). Boys' t-shirts start at €45.90 on Spartoo and girls' tees at €51. Kids' polo shirts match adult construction quality at €63–€91, which is why parents keep buying them season after season.
For growing kids, consider one size up. A boy who measures 120 cm fits a size 6 technically, but a size 7 gives several months of room before a growth spurt makes it too short. Check the full kids' range on the kids' clothing & shoes page.
Common Sizing Issues
Classic Fit runs large. This catches more online shoppers than anything else. You order your usual M and it arrives with room for a second person inside. For your first Classic Fit purchase, go down one size. An L in Classic Fit drapes like an XL from most other brands.
Slim Fit runs small. The tapered waist and narrow sleeves feel tighter than comparable slim fits from Tommy Hilfiger or Lacoste. If your arms are even slightly muscular, you'll notice it immediately. Size up one full size.
Cotton mesh shrinks. Pure cotton mesh polos can lose 5–8% of their size after a hot wash and tumble dry. This matters in a Cyprus summer, where throwing everything in the dryer after a beach day at Mackenzie or Fig Tree Bay feels automatic. Resist. Cold wash at 30°C, air dry on a padded hanger.
Knitwear stretches. Cable-knit sweaters and cotton pullovers relax slightly after wearing. Buy true to size and expect the garment to mold to your body within a few wears. No need to size down.
Tips for Buying Online
A few more practical pointers:
- Check return policies. Spartoo and Rodanos accept returns on most Polo Ralph Lauren items. The official ralphlauren.eu site offers free returns for Cyprus customers, which is useful for sizing experiments.
- Order two sizes if unsure. If the retailer offers free or cheap returns, order both and keep the one that fits. The cost of a return is less than the cost of wearing something that doesn't fit.
- For knitwear and sweaters, refer to the official fit guide for garment-specific measurements beyond the body charts above.
- For kids, buy one size up for growth room, especially for school staples you want to last a full academic year.
Compare prices across all eight retailers on the Polo Ralph Lauren hub. A polo shirt that costs €135 at one retailer might be €85 at another in an identical fit and colour. Getting the right size is half the battle. Getting the right price is the other half.
