What the differences mean

Screen and mounting

The Amazon Echo Show 21 is a 21-inch 1920 x 1080 touchscreen that can go on the wall. The Amazon Echo Show 10 (3rd Gen) is a 10.1-inch 1280 x 800 screen on a motorized base, with no wall mount, and owners describe that base turning to keep them in frame. One replaces a small TV. The other follows you around a counter.

Wi-Fi

Both smart displays have 2.4 GHz Wi-Fi, 5 GHz Wi-Fi and Bluetooth. Only the Amazon Echo Show 21 adds 6 GHz. That is the connectivity edge on the sheet. It does not change Alexa, the camera or the hub radios, which match.

Hub and camera

Neither side wins the hub or the camera. The Amazon Echo Show 10 (3rd Gen) and the Amazon Echo Show 21 both include a Zigbee coordinator, a Thread border router and a Matter bridge, plus a camera with a hardware off switch. Both run Alexa, both list Home Assistant as partial, and neither runs Google Assistant. Warranty is one year on both.

Size on the counter

The Amazon Echo Show 10 (3rd Gen) measures 251 x 230 x 172 mm and weighs 2560 g, a base that has to swing. The Amazon Echo Show 21 measures 540 x 350 x 38 mm and weighs 171 oz, a wide panel meant to hang or stand still. Color choices are listed for the 10-inch model and not for the 21-inch model.

Which one to buy if

What owners say

Owners of both Echo smart displays praise a screen that handles recipes, photos and camera feeds, and both groups complain about on-screen ads and an assistant that still feels unfinished. The feature they single out is not the same. Amazon Echo Show 10 (3rd Gen) owners talk about the motorized base turning the panel to face them for calls and cooking, and they warn that it needs clear space to swivel and cannot be wall-mounted. Amazon Echo Show 21 owners talk about a bright 21-inch panel replacing a kitchen TV, widgets and calendars readable across the room, and sound that many of them end up pairing with a separate speaker. They also say portrait orientation drops the newer assistant.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
