PATTERN GRADING
In our J&O Studio Sewing we use advanced anthropometric knowledge to accurately grade your base size sample pattern into specific size ranges. Whether you require industry-standard grading rules, your company’s established grading system, or assistance in developing a bespoke grading specification, we provide a solution that fits your needs.
Our grading process ensures that the selected grading rules align with your target market sector by considering:
- Price point and retail positioning
- Fabric type and material behavior
- Consumer demographics, including gender, age range, and style preferences
- Garment usage and vanity sizing expectations
With our expertise, your designs will maintain consistency in fit and proportion across all sizes while meeting the expectations of your target audience in terms of comfort, style, and functionality.

Custom Grading Rules for Women’s Wear
When developing a bespoke grading system for women’s fashion, key factors to consider include your target consumer profile—age range, garment usage, and style preferences—as well as your brand’s positioning within the market.
Choosing and refining the size range is especially crucial in women’s wear grading, as it directly impacts brand perception and sales performance. Strategic adjustments to sizing can influence consumer appeal—brands targeting specific demographics may benefit from skewing size ranges slightly smaller or larger, depending on their market sector.
By implementing a tailored grading strategy, brands can enhance customer satisfaction, build brand identity, and drive higher conversion rates.
Precision Grading for Menswear
In menswear grading, sizes typically follow numerical (34, 36, 38, 40, 42, 44… 60) or lettered (S, M, L… XXXL) systems, depending on the type of garment and market positioning. The choice of sizing method is influenced by both customer identity and the brand’s target market, ensuring a fit that aligns with consumer expectations.
When grading men’s clothing, two key measurements require special attention:
Stature – the ratio between chest and waist for proportional fit
Height variations – categorized as short, regular, or long, affecting overall garment length
By fine-tuning these elements, brands can create a well-balanced, market-driven sizing system that enhances fit consistency, brand identity, and customer satisfaction.
Optimized Grading Strategies for Menswear
Research shows that men are less likely to try on garments before purchasing, making precise pattern grading essential for ensuring a consistent and reliable fit. A bespoke grading system allows brands to strategically design size increments that maximize reach across the sizing spectrum, improving customer confidence in fit selection.
Additionally, aligning your size structure with industry standards or competitor sizing helps consumers choose the correct size effortlessly. This approach not only enhances customer satisfaction but also significantly reduces return rates, leading to improved profitability and brand loyalty.
Optimized Grading Solutions for Children’s Wear
For children’s clothing, we recommend using age-based sizing increments rather than height, as market research indicates that height-based sizing can be confusing for consumers. Children’s wear grading can be structured as single sizes or dual sizes, depending on the garment type and target market sector.
To create a well-structured size range, we categorize children’s wear into key age groups:
Babywear (0-2 years)
Kidswear (3-11 years)
Teenswear (12-16 years)
As sizing transitions into older age groups, we recommend introducing an additional base size pattern to accommodate the different growth patterns between genders, ensuring a better fit and improved sizing accuracy.
PLUS SIZE GRADING
Expert Grading Solutions for Plus-Size Fashion
In the fashion industry, true plus size is generally considered to be UK size 18 and above. One of the key factors in plus-size grading is identifying the body shapes of your target customers, as body proportions vary significantly within this market segment.
The plus-size fashion sector offers numerous opportunities for expansion, particularly in niche categories such as plus-size tall garments. If you are extending an existing clothing line beyond size 18, we recommend developing an additional base size pattern to accommodate fit allowances in key areas. Special attention should be given to:
- Armhole shaping
- Shoulder length and across-back width
- Bust, waist, and hip proportions
For brands launching a dedicated plus-size clothing line, we advise starting with a base size pattern in UK 18 or 22, ensuring that grading increments reflect industry standards while providing an optimal fit for the plus-size consumer.
MATERNITY GRADING
Specialized Grading for Maternity Wear
Maternity clothing sizing typically follows standard UK sizes (6, 8, 10, 12, 14, 16), with some brands further segmenting sizes by trimester or pregnancy month. The base size pattern is generally designed for women in the second to third trimester, as many can still wear regular clothing during the first trimester.
For maternity trousers, sizing is based on waist measurements (26, 28, 30, 32), maintaining the pre-pregnancy waist size while incorporating additional allowances for abdominal growth and other body changes.
Bespoke grading is particularly beneficial in maternity fashion, as each woman experiences different body transformations throughout pregnancy. Brands that target specific maternity niches, such as petite maternity wear, plus-size maternity fashion, or trimester-specific designs, can tap into highly profitable market segments.
SPORTSWEAR GRADING
Optimized Grading Solutions for Sportswear
For sportswear grading, the base size pattern is designed with built-in ease allowances to ensure unrestricted movement during physical activity. The type of sport and garment category significantly influence the grading system, as different consumers have varying expectations for fit and performance.
For example, a fitted Lycra top is typically preferred by individuals engaged in high-impact sports, whereas a regular t-shirt may appeal to beginners or those engaging in low-intensity workouts. To meet these different consumer demands, brands may consider adjusting size increments accordingly.
We recommend using a single-size system (e.g., 8, 10, 12, 14, 16) rather than dual sizing, as this provides a more comfortable and precise fit. Additionally, a single-size system allows consumers to progress down the size range as their fitness improves, creating a more motivating shopping experience and increasing the likelihood of repeat purchases.
