Ponte Roma (Ponte di Roma) is a double knit built on an interlock base with extra courses, which gives it a firm, compact body and a subtle horizontal line on the face. It recovers its shape well, resists creasing and holds a cut line, so it is used where a knit has to behave almost like a light suiting fabric. In our library, most ponte weighs 210–320 GSM, and viscose/nylon/spandex is the largest group, followed by cotton/polyester/spandex and polyester/spandex. Ponte is comfortable for pull-on trousers and fitted dresses that need stretch without looking casual. It is heavier and less fluid than jersey, so it is not suited to soft, draped designs, and the amount of stretch in each direction depends on the spandex content.
Viscose/nylon/spandex is our main ponte blend; cotton and polyester blends give a drier hand or a lower-maintenance option.
| Fabric type | Fabric examples | Apparel applications |
|---|---|---|
| Viscose/nylon/spandex ponte | 210–350 GSM, such as LM18001 (65% viscose / 29% nylon / 6% spandex) at 220 GSM and LM18002 at 350 GSM | Dresses, trousers, skirts and smart tops |
| Viscose/spandex ponte | Around 250 GSM, such as KF655 (95% viscose / 5% spandex) | Fitted dresses and tops |
| Cotton/polyester/spandex and cotton/nylon/spandex | 200–320 GSM | Casual trousers, polo shirts and T-shirts |
| Polyester/spandex ponte | 240–300 GSM | Trousers, skirts and knit blazers |
Choose 200–250 GSM for smart tops and polo shirts, 215–300 GSM for dresses and skirts, and 240–350 GSM for pull-on trousers, shorts and knit blazers. Nearly nine in ten ponte qualities in our library weigh 200 GSM or more.
All three are double knits. Compare body, surface and stretch to choose between a fluid, a stable and a sculpted look.

Xiwen Zhang, our co-founder and CEO, recommends these Ponte Roma weights and blends for smart, easy-care garments our customers develop most often, drawing on our knit fabric experience since 2009.

COMFORT WITH A TAILORED LINE
Choose 240–320 GSM ponte for pull-on and straight-leg trousers. Trousers are among the most common uses for ponte in our library. The firm body keeps a pressed-looking leg line, and the spandex lets the trousers move without bagging at the knee.

A DRESS THAT HOLDS ITS SHAPE
215–300 GSM viscose/nylon/spandex ponte works well for sheath and shift dresses. It skims the body without clinging and keeps darts and seams crisp, which suits workwear and occasion dresses in a knit.

SMART CASUAL ON TOP
For smart knit tops and polo shirts, start with 200–300 GSM ponte. It gives a polo or a boat-neck top a neater, more structured look than pique or jersey, and the blend keeps colours rich and even.

LINE OVER THE HIPS
Choose 220–300 GSM ponte for pencil and A-line skirts. The stable double knit keeps the skirt shape over the hips and through the hem, so it can be cut with fewer darts than a woven skirt.

NEAT SHORTS FOR WARM DAYS
250–310 GSM viscose/nylon/spandex ponte works well for tailored knit shorts. It keeps a sharp front crease and clean hems while staying comfortable with an elastic or partly elasticated waist.

TAILORING IN A KNIT
For unlined knit blazers, start with 280–350 GSM ponte at the heavier end of our range. It holds a lapel and a structured shoulder while staying softer and easier to wear than a woven jacket. Fuse fronts and lapels lightly to keep the knit flexible.
No. Ponte Roma is a double knit built on an interlock base. It is firm enough to look tailored, but it keeps the stretch and comfort of a knit.
Not automatically. The stretch in each direction depends on the spandex content and construction; most ponte stretches more across the width than along the length. Check the stretch in both directions on a sample before grading the pattern.
Most ponte trouser qualities in our library weigh 240–320 GSM. Use the heavier end for straight-leg or wide-leg trousers, and around 240–270 GSM for slim, pull-on styles.
Shrinkage in length and width, set separately, because tailored trousers show small changes at the waist and hem; viscose/nylon/spandex ponte at 210–350 GSM is checked with the drying method stated. Add pilling, since trousers rub at the thigh, and washing fastness for dark shades.
