Ship Berth Mattress Sizes and Thickness: How to Measure
Measure berth length and width at both ends and the middle, record corner radii and the maximum allowable thickness, and note any lee cloth or fiddle rails.
Key points
- Dimensions. Measure inside the frame at three points.
- Thickness and fixings. State the maximum thickness under the overhead or rail, and any straps or non-slip needs.
- Send a template. For odd shapes, a cardboard template avoids error.
- What to measure. Record berth length and width at head, middle and foot, corner radius, the clear height above the berth, positions of lee cloths or fiddles, and fastening points.
- Why berths are hard. Ship berths follow the hull, so sides taper and corners curve.
Dimensions
Measure inside the frame at three points. Record the corner shape and any cut-outs.
Thickness and fixings

What to measure
Record berth length and width at head, middle and foot, corner radius, the clear height above the berth, positions of lee cloths or fiddles, and fastening points. Photograph the berth with a tape in view. Send the sheet and photos with your order.

Why berths are hard
Ship berths follow the hull, so sides taper and corners curve. A rectangular mattress leaves gaps or rides up the sides. A template cut from card, with every corner and cut-out marked, solves this more reliably than measurements alone.
Detailed guidance
Ship berths are built around the hull, so shapes vary. Trace each berth on card, mark corner radii, cut-outs and any tapering, and note the clear height above the berth and any lee cloth or fiddle. Check fastening points for straps or non-slip needs.
Choose thickness with the headroom in mind: a thick mattress that leaves no headroom is uncomfortable and unsafe. Record the berth reference, the template and photographs, and label each template so replacements match. For fleets, standardise sizes where possible, and keep spare mattresses of each shape at the base. Check the first delivery against the templates before it goes aboard.
Worked example (illustrative figures)
A berth tapers from 780 mm at the head to 700 mm at the foot with rounded corners. A rectangular 760 mm mattress rides up the sides. A template traced on card, with corner radii and the 100 mm height limit marked, gives a made-to-shape mattress that fits flush.
