Oversized T-Shirt Manufacturer: Fit, Measurements and MOQ Guide
An oversized t-shirt manufacturer cuts a wider, longer, drop-shoulder block from 200–300+ GSM cotton jersey, and the result depends on the measurements you specify, not on the word "oversized". At Sleek Apparels in Dhaka, oversized tees start at 50 pieces per style, so a new brand can prove a fit before committing to a large run.

What is an oversized t-shirt? Oversized vs boxy vs relaxed fit
"Oversized" has no standard definition. One brand's oversized tee is another brand's relaxed fit, and a factory will cut exactly what your paperwork says. Before you send an enquiry, decide which of three silhouettes you want.
| Fit | Body shape | Shoulder | Typical length | Typical use |
|---|---|---|---|---|
| Relaxed | Slightly roomier than a regular tee | Set-in or slight drop | Regular | Everyday basics, retail staples |
| Boxy | Wide, square body | Drop shoulder | Short to regular; hem near the hip | Streetwear, cropped-feel layering |
| Oversized | Widest body, longer sleeves | Pronounced drop shoulder | Regular to long | Streetwear, merch, layering |
Two points trip up first-time buyers. First, silhouette comes from the pattern, not the fabric: a heavy jersey cut on a standard tee block still hangs like a standard tee. Second, oversized is not the same as sizing up. Sizing up a regular block widens the shoulder and lengthens the body in proportion, while a true oversized block changes the proportions on purpose.
Oversized t-shirt dimensions: the measurements to put in your tech pack
Factories work from points of measure, not adjectives. For every size, give at least: half chest, body length, shoulder drop, across-shoulder width, sleeve length, sleeve opening, neck width and rib height. Our tech pack guide covers the full checklist.
| Point of measure (size M, flat, cm) | Regular | Boxy | Oversized |
|---|---|---|---|
| Half chest (armpit to armpit) | 52–54 | 56–59 | 59–63 |
| Body length (high point shoulder to hem) | 70–72 | 66–69 | 71–75 |
| Shoulder drop (seam below natural shoulder) | 0–1 | 3–5 | 4–8 |
| Sleeve length (from shoulder seam) | 21–23 | 22–25 | 24–28 |
| Sleeve opening | 17–18 | 19–21 | 20–23 |
These are indicative starting ranges for streetwear blocks, not a Sleek Apparels standard. The most reliable method is to measure a tee you already love and send us your own measurement chart. We build the pattern and grade the size run from it.
Shrinkage allowance: measure after the wash
Cotton jersey moves when it is washed, so finished measurements must be agreed after washing. Our fabric is pre-washed and pre-shrunk with a shrinkage tolerance of 3%. On a 60 cm half chest that is about 1.8 cm, and on a 72 cm body length about 2.2 cm. Garment dyeing shrinks the piece further, so the block is cut larger to finish at your target measurements.
Dimensional change is normally reported as a percentage of extension or shrinkage after a standard wash and dry procedure [2], and the washing procedures themselves are defined in ISO 6330 [1]. If your retailer or brand requires third-party proof, SGS or Intertek wash and shrinkage test reports can be provided at additional charge, with the lab fees borne by the buyer.
Grading an oversized size run
Oversized blocks do not grade like regular ones. If shoulder drop and sleeve opening simply scale up with the body, the XL ends up looking like a different garment from the S. Agree grade rules for each point of measure up front. Sizes up to 4XL are not a problem for us, in men's, oversized and regular fit, and sizes can be mixed within the MOQ.
Best fabric and GSM for an oversized t-shirt
Fabric weight sets how the shape drapes. Lighter jersey flows and creases, mid-weight holds a boxy line, and heavy jersey stands away from the body. Our GSM guide explains the weight bands in more detail.
| GSM | Hand and drape | Best for |
|---|---|---|
| 200–220 | Soft, fluid; follows the body and creases easily | Relaxed summer tees, lighter oversized fits |
| 240–280 | Structured; holds a boxy shape | Most streetwear oversized and boxy blocks |
| 300+ | Heavy and stiff; holds a square silhouette | Premium and statement streetwear (we quote 320+ as heavyweight) |
For most oversized streetwear tees we work in 100% cotton jersey. CVC interlock at 210–230 GSM is available from stocked fabric with no custom knit run, and a custom knit and dye run for something heavier adds 7–10 days. Do not judge a tee by GSM alone: the neck rib and stitching matter just as much. A heavy body with a thin collar looks cheap and rolls. We prefer coverstitch for hem and collar, with twin-needle available if your spec calls for it. Our heavyweight t-shirt guide goes deeper on block, neck and fabric construction.
Oversized t-shirt manufacturer MOQ, price and lead time from Dhaka
Bangladesh is one of the world's largest apparel exporters: ready-made garments were roughly USD 38.7 billion of USD 48.0 billion total exports in FY2025-26, according to BGMEA data [3]. Scale does not guarantee low minimums, though, so here are our actual terms for oversized tees.
| Item | Sleek Apparels terms |
|---|---|
| MOQ | 50 pieces per style for knit tees. Sizes mixed freely, no minimum per size. If your size run goes up to 4XL, we confirm the minimum when we quote. We confirm how colourways count at quote. |
| Garment dye | Minimum 25 pieces per colour. |
| Price | Heavyweight oversized tee (320+ GSM): USD 11.25–12.50 per piece, freight included, import duties and VAT excluded. Adult regular tees from USD 10.75. Final price confirmed from your tech pack. |
| Sample | USD 60 development per style (USD 85 with branding), plus the garments and courier. The development charge is credited against bulk. |
| Development time | Around 10–12 days. |
| Bulk production | 12–15 days for up to 2,000 pieces, varying by season. Allow roughly 25–35 days from approved sample to shipment. |
| Payment | 50% before production, 50% before shipment. |
| Delivery | Door-to-door with freight in the unit price. The buyer pays import VAT and duties at customs (not DDP). |
We prefer to quote price only after receiving the tech pack, because price depends on fabric, weight, fit, decoration and quantity. If you are not ready for a full tech pack, a measurement chart and a reference photo is enough to start.
Printing, embroidery and finishes on oversized tees
Screen printing and DTF (direct-to-film) are done in-house. Embroidery is handled by a regular partner factory. Branding adds approximately USD 1.50 per piece for screen print and USD 1.65 per piece for embroidery. A decorated sample carries extra development cost on top of the blank sample charge.
Oversized tees give you a larger canvas, so artwork placement needs checking per size: a chest print that sits perfectly on an M can drift low on a 3XL. For washed looks, our acid wash oversized tee is a boxy, drop-shoulder 100% cotton jersey at about 240 GSM. Washed finishes add 3–5 days, and orders are approved against a physical wash-intensity standard because no two washed pieces are identical.
How to sample an oversized t-shirt before bulk
The sample is where fit is won or lost. A reliable sampling loop has five steps, listed below: brief, pattern and sample, measure and wash-test, comment and approve, then deposit and bulk. Do not skip the wash test. A sample that measures perfectly before washing and 3% short afterwards is a fit problem you would otherwise find in 500 finished pieces.
- 1Send your brief. Share a tech pack or, at minimum, a measurement chart from a tee you already like, plus fabric weight, colour and any artwork.
- 2Pattern and development sample. We cut a pattern to your chart and make the sample, which takes around 10–12 days. Development is USD 60 per style (USD 85 with branding), credited against your bulk order.
- 3Measure and wash-test the sample. Measure every point against your chart, then wash it and measure again. This shows the real shrinkage and how the shoulder and body hang.
- 4Comment and approve. Mark corrections, re-sample if needed, then approve the sample as the bulk standard.
- 5Deposit and bulk production. Pay 50% before production; bulk runs generally take 12–15 days for up to 2,000 pieces, varying by season. The remaining 50% is due before shipment.
Common problems with oversized tees and how to prevent them
- Stretched or wavy necklines. A heavy body pulls on a light collar. Specify the rib height and weight, and have the neck width measured on the sample after washing.
- Shoulder drop that looks sloppy. Too deep a drop makes the sleeve sit like a cape. Test your drop on a physical sample rather than judging it from a flat drawing.
- Twisting side seams. Wide blocks in knit fabric can torque after washing. Ask about fabric finishing and compaction, and check the side seams on the wash-tested sample.
- Length shrinking faster than width. Cotton jersey often loses more in length. Build the shrinkage allowance into the length measurement, not just the chest.
- Shade variation between runs. Approve a colour standard with the sample and keep it as the reference for reorders.
Catching these at sample stage costs a few days. Catching them after bulk production costs a reorder.
Questions to ask an oversized t-shirt manufacturer
- Can you work from my own measurement chart rather than your standard block?
- What is your shrinkage tolerance, and is it measured after washing?
- How do you grade shoulder drop and sleeve opening across the size run?
- Is your MOQ per style, per colour, or both, and does my size range change it?
- What is the neck rib weight and the hem and collar stitch type?
- What does development cost, and is it credited against bulk?
- What testing documents can you provide, and who pays for them?
When Sleek Apparels is not the right fit
We are honest about limits. If you need fewer than 50 pieces per style, a made-to-order or print-on-demand route will suit you better. Our facility is BSCI-audited, but we do not hold OEKO-TEX, GOTS, WRAP or ISO certification, and we cannot supply fabric mill certificates. We are also not REX registered, so we cannot provide EU preferential proof of origin; EU and UK buyers should budget for standard duty and import VAT. And when our lines are full, we tell you early rather than overpromise.

Frequently asked questions
- What is the minimum order quantity for oversized t-shirts?
- Our minimum is 50 pieces per style for knit tees such as oversized t-shirts. Sizes can be mixed freely within the minimum, with no minimum per size. If your size run extends to 4XL, we confirm the minimum when we quote. We confirm exactly how colourways count when we quote your tech pack.
- How much does it cost to manufacture oversized t-shirts?
- Our heavyweight oversized tee (320+ GSM) is USD 11.25–12.50 per piece, with freight included to your door and import duties and VAT excluded. Price depends on fabric, GSM, decoration and quantity, so we quote after receiving your tech pack. Screen printing adds about USD 1.50 per piece; embroidery about USD 1.65.
- What GSM is best for an oversized t-shirt?
- For most streetwear blocks, 240–280 GSM gives enough structure to hold a boxy shape while staying wearable. 200–220 GSM drapes softer and looser. 300+ GSM gives a stiff, statement feel. Choose by the silhouette you want, then confirm the neck rib is heavy enough to match the body fabric.
- How long does it take to produce oversized t-shirts in Bangladesh?
- Development sampling takes around 10–12 days. Bulk production generally takes 12–15 days for up to 2,000 pieces, varying by season. A custom knit and dye run adds 7–10 days, and washed finishes add 3–5 days. Allow roughly 25–35 days from approved sample to shipment, plus transit to your market.
- What is the difference between oversized and boxy fit?
- A boxy tee has a wide, square body that is often shorter, with a drop shoulder. An oversized tee is wider overall, usually longer, with longer sleeves and a more pronounced shoulder drop. Both use drop-shoulder patterns; the difference is in the proportions, so specify measurements rather than the label.
- Can you make oversized t-shirts from my own measurements?
- Yes. We ask buyers for their own custom measurement chart, and a tee you already like is the best reference. We build the pattern and grade the size run from it, then you check the sample against your numbers before approving bulk production.
