  If you spend a lot of time on your sailboat – whether you’re a liveaboard or a weekend warrior – chances are, you’ve thought about custom bedding at some point, whether it’s a quilt topper or custom fitted sheets.

Most boat bedding companies require a template in order to ensure the correct size for your custom bedding, which requires that you know how to properly measure your v berth. With our Universal CinchFit Fitted Sheet design, we get it right without needing a template, but for those of you who do want to order custom bedding, or even create your own, here’s how to properly measure your v berth.

While most v berths have essentially the same basic shape (hence the name v berth), the measurements can vary greatly from boat to boat. The key to measuring and cutting raw materials to fit your v berth  is to get the angles correct.  Here are the important measurements and steps to successfully do this.

## Traditional V Berth Shape – Symmetrical If you are making a product that fits on top of your v berth – such as a quilt, topper, etc., then the two measurements you’ll need to determine the total amount of material needed are:

• The width of the Head (H)
• The length between the Foot and the Head (Center)

(Note: If you are making a fitted product such as a fitted sheet, you will also need to add additional length to all measurements to account for both mattress depth and seam allowances.)

Step 1: Measure the Head Width. Divide this number in half.

Step 2: Measure the Total Length between the Foot and Head.

Step 3: Measure the Foot Width. Divide this number in half.

Step 4: Lay out your raw material in a large open space.

Step 5: Measure the material to determine which side is long enough to be used for the Head and which side is long enough to be used for the Total Length of your material.  Place the material so that the Head side of the material is facing you.

Step 6: Mark the exact center of the material at the Head end with fabric chalk (Head – Center). Mark the exact center of the material at the Foot end with fabric chalk (Foot – Center).

Step 7: Using the measurement you calculated in Step 1 (1/2 Head Width), measure from the Head Center to the left the number of inches you calculated as half the Head Width and mark this spot (Head – Left). Measure from the center to the right the number of inches you calculated as half of the Head Width and mark this spot (Head – Right).

Step 8: Using the measurement you calculated in Step 2 (Total Length) measure from the Head Center towards the Foot end the number of inches you calculated as Total Length and mark this spot.  (Foot Center/Total Length) Trim material if needed so material is the correct Total Length.

Step 9: Facing the Foot End of the material and using the measurement you calculated in Step 3 (1/2 Foot Width) measure from the Foot Center  to the left the number of inches you calculated as half of the Foot Width. (Foot – Right) Measure from the Foot Center out to the right the number of inches you calculated as half the Foot Width and mark this spot.  (Foot – Left)

Step 10: To achieve the exact, correct angle for your raw material just connect the (Head Left) to the (Foot Left)  using a ruler, board, straight edge. Then connect the (Head Right) to the (Foot Right).

(Note: If you are using fabric, the same process can be more easily accomplished by folding the fabric in half at the center points and then measuring points, connecting points and then cutting two layers of fabric at the same time.)

## Asymmetrical or Rounded V Berth Shapes Although more difficult, these shapes can be measured accurately.

Step 1: Measure Total Length.

Step 3: Measure Foot Width.

Step 4: Measure the Length of all Sides (Side Lengths).

Step 5: For each Side Length, also measure the Total Width at that point.

Step 6: For each Side Length also measure the Length from the Foot where the Side Width changes.
