Armhole Depth Grading Notes for Oversized Tee OEM Buyers

Oversized tees are not just bigger sizes—they require a deliberate armhole depth strategy. If the armhole drops too low, the tee looks sloppy and restricts movement; too high, and it loses the relaxed drape buyers expect. This guide gives OEM buyers concrete grading notes to include in tech packs and RFQs.

Why does armhole depth grading matter for oversized tees?

Armhole depth is the vertical distance from the shoulder point to the underarm seam. On oversized silhouettes, this measurement controls how the sleeve hangs and how the body falls. A common mistake is to apply standard grading rules (e.g., +0.5 cm per size) to oversized fits, which can create a disproportionate drop. Instead, oversized tees often need a non-linear grade: smaller sizes get a smaller increment, larger sizes get a larger increment, or the armhole depth is fixed relative to body length.

What armhole depth specs should OEM buyers include in an RFQ?

To get accurate samples and bulk, your RFQ should include:

• Base size armhole depth (e.g., 25 cm for size M)
• Grade rule per size (e.g., +0.6 cm for S to L, +1.0 cm for XL and up)
• Relationship to chest width and body length (e.g., armhole depth = 30% of body length)
• Tolerance (e.g., ±0.5 cm)
• Measurement method (curved along seam vs. straight drop)

Weavnora recommends buyers send a reference garment or detailed measurement chart. Our team can then propose a grading table before sampling.

How does fabric weight (GSM) affect armhole depth grading?

Heavier fabrics (220–300 GSM 100% cotton) drape differently than lightweight jersey. A deep armhole on a 280 GSM tee will pull more at the underarm, so the grade may need to be slightly reduced compared to a 180 GSM tee. Weavnora’s standard tee programs lock 220–300 GSM, and our pattern team adjusts armhole depth based on fabric weight and wash shrinkage.

What are common armhole depth grading mistakes to avoid?

• Using the same grade as a regular fit tee
• Ignoring sleeve cap height when changing armhole depth
• Not accounting for garment dye or wash shrinkage
• Specifying armhole depth without a measurement method
• Forgetting to grade the armhole curve shape, not just the depth

Armhole depth grading checklist for oversized tee OEM buyers

1. Define base size (e.g., M) armhole depth in cm.
2. Set grade increments per size or size range.
3. Specify measurement method: straight drop from shoulder point to underarm seam, or along curve.
4. Include tolerance (e.g., ±0.5 cm).
5. Note fabric GSM and any wash process that affects shrinkage.
6. Request a graded spec sheet from the factory before sampling.
7. Approve a fit sample before bulk.

Weavnora confirmed scope for oversized tee OEM

Common buyer QA practice: “We always ask the factory to send a graded measurement chart with armhole depth for every size before they cut the sample. That way we catch grading errors before spending money on a fit sample.”

Compare: standard tee vs. oversized tee armhole depth grading

Choosing the right armhole depth grade is a trade-off between drape and mobility. A deeper armhole gives more slouch but can restrict arm lift; a shallower one is cleaner but less oversized. Weavnora helps buyers balance these factors with sample iterations.
