XLT
Initialism of extra large tall (the manufactured size or an item of that size).
XLT: the tall person's standard size in ready-to-wear
XLT stands for extra large tall, a garment size designation used in the textile and apparel industry to accommodate people who are both large in width and above average in height. Unlike base XL, which assumes a standard inseam of roughly 32 to 34 inches depending on the garment category, XLT adds 2 to 4 inches of length in the sleeves, torso, and legs. This size bracket typically targets men and women standing 6 feet 2 inches or taller with corresponding shoulder width and chest or bust measurements.
The sizing system emerged as manufacturers recognized that simply grading up a standard large created proportional errors. A large shirt enlarged uniformly becomes too wide in the shoulder relative to sleeve length. XLT addresses this by adding length preferentially to the vertical dimension. Sleeve pitch, armhole depth, and inseam all grow, while width increases more modestly. The standard grading increment for tall variants is roughly 1 inch added to sleeve length per size step and 1.5 to 2 inches to inseam.
XLT appears most commonly in menswear, where tall variants account for a meaningful market segment in dress shirts, casual shirts, and trousers. Many manufacturers offer XLT in basics like underwear, t-shirts, and sweatshirts, though premium brands are more likely to maintain the range. Womenswear sizing is less standardized; some makers use XLT, others use separate tall lines, and some avoid tall sizing altogether, assuming the market is negligible.
Production of XLT requires separate pattern grading and fabric allocation. A maker cannot simply cut XL pieces from the same marker as standard sizes without waste or shortage. This adds complexity to lay planning and cutting room operations. Inventory forecasting becomes critical; XLT typically sells in lower volume than standard XL, so overstock ties up capital while understock loses sales to competitors who stock the size.
XLT is often conflated with extended sizing, which refers to larger base widths regardless of height. The distinction matters: a person who is 5 feet 8 inches with a 48-inch chest fits XL, not XLT. Conversely, a 6 foot 4 inch person with a 42-inch chest may need XLT but not a conventional XL in width. Some retailers and makers use T or XT as shorthand notation on tags and in systems.
