Hi there,

Thank you for your message.

Unfortunately there is no setting in Elementor to do this, the only way is to add a custom class to the page builder row and add CSS code to make the icon boxes equal in height.

You can do this by following these steps:

1. Edit the page builder row that hold the 3 columns and click the "Advanced" tab
2. Add "equal-height" to the "CSS Classes" input field
3. Copy/paste the following CSS code to Appearance -> Customize -> Additional CSS:

/* fix to make icon boxes equal height */
.equal-height .elementor-container > .elementor-column {
	height: auto;
}
.equal-height .elementor-widget-container,
.equal-height .elementor-element {
	height: 100%;
}

.equal-height .icon-box {
	height: 100%;
	display: flex;
	align-items: center;
}

Please see first attached image for step 1 and 2.

Hope this helps, let me know if you have any questions.
