Floral Cotton Fabric for Fitted Sheets: Pocket Depth, Elastic Layout & Finished Size Control

Short answer: A fitted-sheet fabric order should begin with the finished mattress dimensions and the sheet’s pocket/elastic design—not with fabric width alone. Buyers need to define mattress length, width and height, under-mattress tuck allowance, seam placement, elastic layout, finished dimensions after the specified care procedure, floral-pattern direction and cutting yield. The live record for Nantong Oulai FAB-0002 identifies 100% cotton floral printed fabric, a 150–250 cm reference width range, 100–140 gsm reference weight range and a 100 m MOQ; the chosen values must be confirmed for the actual fitted-sheet design.

Why is a fitted sheet more than a rectangular fabric panel?

A finished fitted sheet is a three-dimensional product. Its top panel must cover the mattress length and width, while its side and end walls must accommodate mattress height, the corner construction and the portion retained underneath. Elastic distribution then determines how the perimeter gathers and stays in place.

“Queen,” “King” or “30 cm pocket” is not enough for production because bed-size names vary by market and brand, and mattress toppers can change the real stack height. The buyer should provide dimensions in a declared unit and an approved mattress or rigid mock-up where possible.

Input	What to state	Why it changes the fabric order
Mattress footprint	Exact length and width	Defines the top surface and corner positions
Mattress stack height	Mattress plus intended topper/pad condition	Drives wall and pocket depth
Under-mattress tuck	Brand-approved retained depth	Affects cut size and fit security
Corner method	Boxed, shaped or other approved construction	Changes cutting geometry and seam length
Elastic layout	Full perimeter, selected zones or corners; relaxed/extended specification	Changes gathering and installation
Care procedure	Wash/dry sequence and cycles	Determines dimensional allowance and final-size approval

Which live product facts are available for FAB-0002?

The current Shopify record identifies FAB-0002 as floral printed 100% cotton for fitted sheets, mattress covers and coordinated bedding. Custom printing, colour matching and OEM/ODM development are available. Ordering references are:

• MOQ: 100 metres, with final MOQ confirmed for the selected design;
• Reference width: 150–250 cm, confirmed by item;
• Reference mass: 100–140 gsm, confirmed by item;
• Typical lead time: 7–10 days after specification and sample approval;
• Packaging: roll packed or customized.

These are ranges and commercial references, not the final specification. Nantong Oulai should confirm the selected construction, usable width, finished mass, print, quantity, packing and delivery terms in the quotation.

How do mattress height and pocket depth become a cut specification?

Keep the variables separate. Let the buyer state mattress height and any topper condition. Then define an additional under-mattress retention allowance and the seam/hem construction. The resulting pocket depth is a design decision; it is not automatically equal to mattress height, and there is no universal extra allowance that fits every elastic system.

Before bulk cutting, the supplier should issue a dimensioned pattern showing:

• top-panel length and width;
• side/end depth before and after hemming;
• corner cut-out geometry and seam allowance;
• elastic casing or attachment line;
• notches and pattern direction;
• target finished dimensions before and after the declared care trial.

Mark warp and weft on every prototype. Their dimensional changes can differ, so rotating a pattern piece may change both fit and floral direction. Oulai’s guide to warp and weft in bedding fabric explains why direction belongs in the specification.

How should the elastic system be approved?

“Elasticated fitted sheet” does not define the elastic. The RFQ should state whether elastic runs around the full perimeter, only at corners or in specified zones. Record elastic material declaration where needed, width, relaxed length, extension requirement, attachment or casing method, join position and stitch construction. Do not invent an extension percentage: approve it on the target mattress mock-up and verify recovery after the agreed care process.

Elastic decision	Approval evidence	Failure to watch
Distribution	Dimensioned perimeter drawing	Uneven gathering or loose sides
Relaxed/extended length	Measured elastic and installed prototype	Excessive installation force or poor retention
Attachment	Seam sample and stitch specification	Skipped stitches, twisting or elastic exposure
Post-care recovery	Prototype check after agreed wash/dry cycles	Permanent elongation or distorted corners

How do floral repeat and direction affect a fitted sheet?

Identify whether the floral design is directional, non-directional or engineered. A one-way floral may require every top and wall component to follow the same head-to-foot direction, limiting rotation during marker planning. Large repeats can also shift motif placement at corner seams and increase matching waste.

Lock these print fields before quotation:

• artwork file and revision;
• repeat height and width;
• one-way or allowable rotation rule;
• top-panel and side-wall motif orientation;
• colour standard and approved strike-off;
• usable printed width and selvedge exclusion;
• bow/skew or placement criteria where relevant.

For a fuller layout method, see Directional vs Non-Directional vs Engineered Prints. The present article uses those principles specifically for the three-dimensional fitted-sheet product.

Which measurements and tests support final-size control?

ASTM D3774 provides an official method for measuring full and usable textile-fabric width, while ASTM D3776/D3776M covers mass per unit area. For laundering effects, ISO 6330 specifies domestic washing and drying procedures; ISO 3759 covers preparation, marking and measurement, and ISO 5077 covers determination of dimensional change.

For a printed fitted-sheet programme, ISO 105-C06 can support colourfastness-to-laundering evaluation and ISO 105-X12 can support rubbing evaluation. These are test methods, not universal pass grades. The RFQ should name the method/procedure, specimen, number of cycles, assessment, acceptance criteria and decision rule.

Test both flat fabric and the sewn prototype where the risk warrants it. The finished prototype reveals corner distortion, seam interaction, elastic recovery and actual mattress fit that a flat swatch cannot show.

What should the fitted-sheet prototype review include?

1. Installation: confirm the sheet can be fitted without unreasonable force.
2. Top-panel alignment: check warp/weft orientation and floral direction.
3. Corner seating: verify seams align with the mattress corners.
4. Side-wall coverage: confirm the required depth around all sides.
5. Under-mattress retention: inspect tuck and elastic gathering.
6. Surface appearance: look for excessive puckering, print distortion or seam twisting.
7. Post-care fit: repeat the fit check after the specified wash/dry cycles.
8. Record: seal an approved prototype with BOM, pattern and artwork versions.

What belongs in the FAB-0002 RFQ?

• Product reference FAB-0002 and destination market
• 100% cotton requirement and order-specific fibre evidence
• Exact mattress length, width and stack height
• Pocket/tuck design and corner construction
• Elastic layout, dimensions, attachment and recovery requirement
• Chosen finished GSM and usable width within the confirmed item range
• Floral artwork, repeat, direction and strike-off approval
• Wash/dry procedure, dimensional-change criteria and prototype fit method
• Finished label, packaging, roll/lot traceability and quantity
• MOQ, price, lead time and delivery terms reconfirmed in the quotation

When estimating metres, combine the approved pattern with usable width, print repeat, one-way restrictions, shrinkage allowance and cutting waste. The related guide on calculating bedding fabric order quantity provides the broader framework.

Frequently asked questions

Is pocket depth the same as mattress height?

Not necessarily. Pocket design may also include an under-mattress retention portion plus seam and hem construction. Define each dimension rather than relying on a single marketing number.

Can the 150–250 cm width range be used as the cutting width?

No. It is the product page’s reference range. The order must confirm the chosen finished and usable width, including how selvedges are treated.

Does 100–140 gsm determine fitted-sheet quality?

No. GSM is one specification field. Construction, width, print, dimensional behaviour, seam design, elastic system and finished fit also require approval.

Does 100% cotton mean the elasticated finished sheet is 100% cotton?

The live page describes the fabric as 100% cotton. A finished fitted sheet can include elastic, sewing thread, labels or other components. Destination-market labelling should be reviewed for the complete product and applicable trim rules.

Does FAB-0002 carry a verified product certification?

The live product record does not establish a product-specific certification. Do not extend a company, facility or supplier scope certificate to this fabric or order without the applicable evidence.
