DNA test sites display your DNA match count in different places, and at Ancestry, the match count is a bit hidden. Once you know where to look, and know why it might not be displaying, it’s easy to remember.
How to find your AncestryDNA Match Count using a desktop computer:
Step 1 – Go to https://www.ancestry.com and Login to your account
Step 2 – On the Ancestry homepage, Select DNA from the top menu bar, then Select DNA Matches from the dropdown menu

Step 3 – Make sure your window is expanded large enough to display all relevant information. In the image below, the window is too small to show to Ancestry’s Filters. Right click the corner of the window and drag it away to enlarge the window.

In the image below, the screen has been enlarged and you can see the Filter by menu options.

Step 4 – Select the Shared DNA option from the Filter by menu

Step 5 – Your total AncestryDNA Match Count is the number in parentheses after All matches. This number is the total of your Close matches-4th cousin or closer AND your Distant matches.
If you want to look at matches who share some specified range of centiMorgans of DNA, use the Custom centimorgan range. Ancestry will not display a count of how many matches you have in this range.

How to find your DNA Match Count using the Ancestry app on a tablet or mobile device:
Your steps will vary by device, but in essence you’ll need to:
Step 1 – Open the Ancestry app on your device
Step 2 – Find your DNA Matches page (this may be from a menu bar with a DNA icon, it may be from the More menu, the icon with three horizontal lines).
Step 3 – Select Filters
Step 4 – Select Shared DNA.
Step 5 – Look at the All Matches number for your total DNA match count. If you can’t see the entire image, touch the screen and drag the image up to show the entire Shared DNA menu.
This is what it looks like on my mobile-device:

Finding your total number of DNA matches is a basic need, but it’s so frustrating when you’re in a hurry and can’t quickly remember how to do it at different DNA sites. Best with your DNA research!
