RVs, boats, adjustable and antique beds do not fit standard sheets. Here is how a buyer turns an odd bed into a manufacturable spec — measure, tolerance, shrinkage, tech pack, MOQ and a fit-checked sample.
RVs, boats, adjustable and antique beds do not fit standard sheets — an RV Queen is 60 × 75 in, not 60 × 80, and a yacht V-berth has tapered, radiused corners. Custom sizes are an OEM capability, and the whole job is turning an odd bed into a manufacturable spec: measure length by width by height, add pocket depth or drop, state a tolerance and a shrinkage allowance, put it in a tech pack, agree the MOQ, and fit-check a pre-production sample on the actual bed before bulk.
Where non-standard sizes come from
| Bed type | Typical quirk | Key measurement to give | Product affected |
|---|---|---|---|
| RV / camper | Shorter than standard (RV Queen 60 × 75 in vs 60 × 80); many bunk widths | Exact L × W × height in cm; note cut/radiused corners | Fitted sheet, flat sheet, duvet cover |
| Boat / yacht | Tapered, angled or V-berth; radius or cut corners | L × W at multiple points + height; corner radius/angle | Fitted sheet (cut to shape), valance, cover |
| Adjustable / split king | Two Twin XL mattresses that articulate independently | Each half L × W × height; confirm two fitted + one oversized flat | Two fitted sheets, flat sheet, split-top duvet |
| Antique / oversized | Metric or legacy sizes; non-standard length | Exact L × W × height in cm (do not assume a named size) | Fitted sheet, cover, bed skirt |
| Extra-deep mattress | Tall pillow-top/hybrid + topper (15–18 in+) | Mattress height, then pocket depth = height + 5–7 cm | Fitted sheet (deep pocket) |
| Crib / cot | Small, safety-critical snug fit | Exact L × W × height; OEKO-TEX Class 1 (baby) | Fitted sheet, mattress protector |
How to measure for a custom order
Measure three dimensions on a bare, uncompressed mattress — length by width by height — at least on two sides to confirm consistency, and include any built-in pillow-top. For fitted sheets, set pocket depth equal to the mattress height plus about 5–7 cm (2–3 in) so the sheet tucks and grips. For radiused or cut corners (boats, some RVs), record the corner type and radius so the panel is cut to shape rather than gathered. For duvet covers, measure the made-up drop over the actual bed, or match the insert and add slight ease. Then protect the fit two ways: a stated manufacturing tolerance (typically ±1–2 cm on finished dimensions) and a shrinkage allowance — specify pre-shrunk/Sanforized cotton (under about 1% residual on woven) and have the factory cut oversize, validated on a wash-tested sample.
The OEM reality: MOQ, tech pack and sample
Custom sizes are made to order, not off the shelf. Generic OEM minimums often run around 300 units per size; BeddingTextilePro offers a 100-set trial MOQ per custom size so you can validate fit and market before committing to bulk. The buyer supplies a tech pack — exact dimensions in centimeters, pocket depth, corner shape and radius, tolerance, shrinkage allowance, fabric (weave and GSM or thread count), color, labeling and packaging — and a pre-production sample is fit-checked on the actual bed before the bulk run. Because custom sizing adds pattern and sampling work, expect a longer lead time and a higher unit cost than stock sizes; the trial MOQ and sample step contain that risk.
How to spec a custom-size order
From odd bed to accepted bulk
- 01
1 · Identify the bed and measure
Measure length × width × height in cm (and corner radius/shape) on the bare, uncompressed mattress at multiple points.
- 02
2 · Decide products and add allowances
Pick fitted / flat / duvet / cover / skirt; add pocket depth (height + 5–7 cm) and the made-up drop.
- 03
3 · Build a tech pack
Exact centimeters, pocket depth, corner shape, a ±1–2 cm tolerance, and a shrinkage allowance (pre-shrunk fabric); attach a photo or sketch of odd shapes.
- 04
4 · Confirm MOQ, fabric and certification
Trial MOQ (BeddingTextilePro: 100 sets per size), weave (percale/sateen) and GSM or thread count, and OEKO-TEX STANDARD 100 (Class 1 for baby).
- 05
5 · Make a sample, fit-check, then bulk
Produce a pre-production sample, fit-check it on the actual bed, correct the pattern, then release the bulk order.
A weird bed is just three numbers and a corner shape. Measure length, width and height, add depth or drop, write a tolerance and a shrink allowance — then prove it on a sample fitted to the real bed.

Frequently asked questions
- What is the minimum order for a custom size?
- Custom sizes are OEM/ODM, so they carry a per-size MOQ. Typical industry minimums run around 300 units per SKU; BeddingTextilePro offers a 100-set trial MOQ per custom size so you can validate fit and market before committing to bulk.
- What exactly goes in the tech pack?
- Exact length × width × height in centimeters, pocket depth, corner shape and radius, finished-size tolerance (±1–2 cm), shrinkage allowance, fabric (weave plus GSM or thread count), color, labels and care, and packaging. Attach a photo or sketch of any odd shape.
- How do you stop custom sheets shrinking out of fit?
- Specify pre-shrunk/Sanforized cotton (under about 1% dimensional change on woven per AATCC TM135 / ISO 6330), have the factory cut oversize with a small allowance, and confirm on a wash-tested pre-production sample before bulk.
- Do all products need custom cutting, or just fitted sheets?
- Fitted sheets are most affected (pocket depth plus footprint or shape). Flat sheets are oversized for the drop, duvet covers sized to the made-up drop or insert, plus pillowcases and bed skirts to the frame. Order only what the odd geometry actually requires.
- How much longer and costlier is custom versus standard?
- Custom adds pattern-making and sampling, so expect a longer lead time and a higher unit cost than stock sizes. The trial-MOQ and pre-production sample step contains that risk before you scale.
