Gramicci Size Guide UK: What Size Am I in Gramicci? Fit Advice, Fabric Details & Brand Comparison

ounded in California in the 1980s and now designed in Japan, Gramicci has become a cult favourite for those who love functionality, utility styling, and comfort-driven silhouettes. From climbing trousers with built-in belts to streetwear staples like gusseted shorts and outdoor jackets, Gramicci offers style with technical heritage.

But like many utility or outdoors brands with global distribution, Gramicci’s sizing isn’t always straightforward—especially for UK shoppers. With influences from American casualwear and Japanese fashion structure, their garments can run large, slim, short, or relaxed depending on the model and region.

At Tellar.co.uk, we’ve analysed Gramicci’s entire fit structure and compared it to 1,500+ global brands. Whether you’re looking at trousers, shorts, or outerwear, you can now get your personalised Gramicci size recommendation in seconds—based on your measurements or known brand sizes.

Start here to get your most accurate size match in Gramicci.

Is Gramicci True to Size?

Gramicci sizing leans towards a relaxed or oversized fit, especially in the brand’s trousers and shorts. However, the fit can vary between American heritage models and Japanese-designed cuts.

Here’s what to expect:

Trousers and shorts often include an elasticated waistband and built-in webbing belt, which adds flexibility
Most styles have a relaxed leg, sometimes tapered or slightly cropped
Jackets and shirts are boxy and roomy, in line with Japanese streetwear trends
Some items are labelled as “Asian fit” or “Japan sizing”—these run narrower and shorter than Western sizing

Tellar.co.uk automatically detects the product type and regional sizing to help you avoid ordering the wrong fit.

Fit Notes by Garment Type

Trousers (Original G-Pant, NN-Pant, Loose Tapered)

G-Pants: The classic model. Roomy seat and thigh with tapering below the knee. Cropped inseam.
NN-Pants: Slimmer cut. Designed to be more fitted but still relaxed through the seat.
Loose Tapered Pants: Wider in the hip and thigh, strong taper from knee to ankle. Modern streetwear fit.

If you typically wear a 30" waist in Weekday or Uniqlo, you may need a size Small in Gramicci—but the belt allows up to 2 inches of flexibility either way.

Shorts (G-Short, Shell Gear Shorts)

G-Shorts are wide through the thigh, made for movement
Length varies by model—some hit above the knee (7”), others longer (9–10”)
Shell styles made with nylon tend to have less give than cotton twill options

Outerwear & Shirts

Often cut boxy and short, in line with Japanese streetwear silhouette
Shoulders run wide, sleeves are slightly cropped
Best to size down if you prefer a closer fit—but check the fabric and model notes

Real Fit Feedback from UK Shoppers

“I wear a 32 in Levi’s but needed a Small in Gramicci—loved the built-in belt.”
“Their NN-Pants ran tighter than expected, but Tellar flagged it. I sized up and it was perfect.”
“The G-Shorts are wide and comfy, but short in the inseam. Wouldn’t have known without Tellar’s fit check.”
