What Is a Fish Bump Board?
A fish bump board is a simple measuring device that you place a fish on to get its length. They can be made of wood, plastic, or metal and range in length depending on the species of fish that they are made for. Bump boards are usually flat or concave with a raised edge or lip to place the fish against.
Bump boards will usually measure fish in quarter-inch increments, giving you a very accurate length measurement in seconds.
This can be extremely important in situations like fishing tournaments or in areas where there are length slot requirements for the fish that you can keep.
How to Use a Bump Board For Fishing
One of the biggest benefits of a bump board is just how easy they are to use.
To properly use one, find the raised edge or lip on one end of the board. This is where you will place the lips of the fish.
Before you lay the fish down, however, wet the board to help protect the slime coating of the fish.
Ensure that the fish lays flat on the board, and with its mouth against the raised edge, measure where the end of the tail touches the furthest measuring mark.
With the mouth of the fish at the starting point and the tail at the measuring marks, you can quickly and easily get a quick length measurement for your catch.
Fishing bump boards are an essential piece of tackle that really help with tournaments, fishing regulations, or even just to record the length of your best catches.

Why are bump boards popular in kayak tournaments?
Bump boards are so popular in kayak tournaments because of the catch-photo-release method that most operate on.
Kayak anglers must measure their fish, take a photo, and then release it so a quality bump board is essential in most kayak tournaments.
It can be difficult to get an accurate weight on bass from a sitting position in a kayak…so instead, most kayak anglers and official kayak tournaments use a bump board to get an overall length.

It’s approved by the KBF and most other kayak tournament trails and features a deep trough that cradles the fish so they don’t slide off.

How to Make Your Own Fish Bump Board
Although bump boards are generally inexpensive, making your own fish bump board can be a fun and easy way to save some money and customize one to your liking.
They can be easily made at home with a little bit of preparation and work.
Bump boards can be made out of a variety of different materials and in different lengths and sizes. A bump board will be anywhere from 30 to 60+ inches long and 1 to 6 inches wide, depending on the material and fish species you intend to use it for.
To make a bump board out of PVC, you will first need to acquire a 4″-8″ PVC pipe that is at least 36 inches long.
Cut a concave section of the pipe down the entire length, creating a semi-circle or ‘cradle‘ shape. This is the base of the board.
Next, take a tape measure and carefully mark out the measurement points. Use a permanent marker to ensure that the marks do not come off your board when wet and in use.
You can also etch these marks into your board to provide even more durability.
Lastly, you’ll need to attach an end piece on the far left side of the board. This is a vertical piece used to keep the fish from sliding off the end and ensures you get an accurate measurement.
With your flat piece of material properly marked with measurements and a defined starting point, your bump board is ready to be put to use!
If you intend to use your own homemade bump board in a fishing tournament, be sure to check with tournament officials. They may need to certify your board, or they may require a specific style and type of board for all participating anglers.
Frequently Asked Questions
Do you pinch the tail when measuring fish?
The proper length of a fish is the furthest point on the fish, open or closed. This often means that the tail can be pinched in order to get the longest length possible, but every state, area, or tournament may have different requirements when measuring fish on a bump board.
For some saltwater species, you only measure ‘to the fork‘, in which case you do not pinch the tail. Always be sure to check the local rules and regulations for where you are fishing.
How do you measure a muskie?
Muskies are measured much like any other fish species, and the total length is done from the tip of their snouts to the tip of the upper lobe of their tail. This will give you the longest overall length of a muskie and it is best done using a bump board.
Because muskie can grow in excess of 50 inches, you need a really big bump board for those once-in-a-lifetime fish!
