With thousands of Bible editions ranging from "Pocket" to "Extra Large Study" versions, there is no such thing as a "standard" size. A cover that is too small won’t zip, and one that is too large allows the Bible to slide around, damaging the spine.
Follow this simple guide to measuring your Bible properly so you can shop with confidence.
What You’ll Need
- Your Bible
- A physical ruler or measuring tape (avoid using "phone apps" for this, as they can be slightly off)
- A piece of paper to jot down the dimensions
The Three Essential Measurements
1. Measure the Height
Place your Bible flat on a table. Measure from the very top of the cover to the very bottom.
- Pro Tip: Do not measure the pages; measure the outer cover. Study Bibles often have "yapp" edges (edges that hang over the pages), and you need to account for those.
2. Measure the Width
Measure from the edge of the spine to the outer edge of the front cover.
- Pro Tip: Make sure the Bible is closed naturally. Don't press it down flat, as this can slightly distort the width.
3. Measure the Spine (Thickness)
This is where most people go wrong. Stand your Bible up on its end and measure the width of the spine itself.
- Pro Tip: If you keep a Christian notebook or a prayer journal tucked inside your Bible, measure them together to ensure the cover can accommodate the extra bulk.
The "Wiggle Room" Rule
Once you have your measurements, you need to add a small buffer. If your Bible is exactly 23cm tall and you buy a 23cm cover, the zipper will likely rub against the corners of your Bible and damage them.
The Golden Rule: Choose a cover that is at least 1cm to 2cm larger than your Bible’s dimensions.
Finding Your Size Category
In our store, we generally categorize our Bible cases into four main groups. Compare your measurements to these general ranges:
Size
Small: 23x16x4cm
Medium: 24x17x4cm
Large: 25x17x5cm
Extra Large: 28x20x5cm
Still Unsure?
If your measurements are right on the line between two sizes, always go for the larger size. This allows you to tuck in a few pens or a slim scripture journal without straining the zipper.
