Best Fish Ruler
Fish rulers are used by anglers to measure the fish they catch. It is important that you choose the proper fish ruler. This is to make sure the fish that does not meet the legal length is freed. Keeping a fish that is shorter than the standard length might result in getting a ticket and cost you a fine. Stretching and folding tape fish rulers that are made of plastics have tendencies to shrink when exposed to high temperatures. As a result, it could give you an erroneous measurement. Like any other purchase, buying a fish ruler has many considerations. It is always important to choose the right fishing ruler for you. Nowadays, there are countless fish rulers on the market and finding the best one that will suit your style and requirement is never easy.

Expert Interviews & Opinions

There are two measurements needed when measuring freshwater fish. These are measuring the girth and getting the total length of the fish. The total length refers to the utmost length of the fish. When getting the total length measurement, make sure that the mouth of the fish is closed while its tail is closed. It is not advised to use a flexible fish ruler and measure the fish by its curve. The perfect way to achieve the total length of the freshwater fish is to move up its snout on a vertical surface with tail shut. The freshwater fish should be positioned along a fish ruler.
In some cases, the rules require the angler to get the fork length of the fish. This is also called the standard length and is measured up to the last fleshy part of the fish. Some anglers prefer the standard length since it is not easily affected by slight damages to the tail.
On the other hand, to get the girth measurement, it is best to use a fabric fish ruler like the ones used by tailors. The girth measurement is the same as taking the circumference of the human waist. To do this, you can lift the fish and put a piece of the flexible fish ruler under it. Make sure that the fish is lying flat while the ruler is positioned on its deepest part. Wrap the flexible fish ruler or measuring tape around and fold its fins if necessary. Spot the point where the line of the flexible ruler crosses. After that place the marked spot on the ruler and get the girth.
Other Factors to Consider

Style
There are many fish rulers on our list that even have pictures, names, and descriptions of the type of fish above its measurement. This helps you know the average size of the fish you have caught and is a good reference while you are out fishing to have. Those rulers have been created to help benefit even beginner fishermen to reference from.
