# Combination Calculator to Find All Possible Combinations of Numbers or Letters

This combination generator will quickly find and list all possible combinations of up to 7 letters or numbers, or a combination of letters and numbers.

Plus, you can even choose to have the result set sorted in ascending or descending order.

Finally, you can switch between having the results displayed in a field (for copying and pasting) and a scrollable, numbered table.

## Combination Calculator

Find all possible combinations for up to 7 numbers, letters, or a combination of both.

#### Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

#### Why Limit The Combinations To Only 7?

As you can see from the following chart, beyond 7 characters, the possible combinations become too large to be practical for an online calculator.

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".
