The Blog Module "Grid" view (selected in Blog Module > Design > Layout > Layout) article "boxes" are not the same height initially - because each article/post can contain a different amount of content even if only Title of the post is shown. Longer post Title size on one Post can results in a "taller" article "box" when comparing it to other "boxes".

To equalize all articles first add a custom CSS class "et_blog_grid_equal_height" to:

Blog Settings > Advanced > CSS ID & Classes > CSS Class

Then insert and save the following JavaScript code into Divi > Theme Options > Integration > Add code to the < head > of your blog :

<script>
(function($) {
$(document).ready(function() {
$(window).resize(function() {
$('.et_blog_grid_equal_height').each(function() {
equalise_articles($(this));
});
});

$('.et_blog_grid_equal_height').each(function() {
var blog = $(this);

equalise_articles($(this));

var observer = new MutationObserver(function(mutations) {
equalise_articles(blog);
});

var config = {
subtree: true,
childList: true
};

observer.observe(blog[0], config);
});

function equalise_articles(blog) {
var articles = blog.find('article');
var heights = [];

articles.each(function() {
var height = 0;
height += ($(this).find('.et_pb_image_container, .et_main_video_container').length != 0) ? $(this).find('.et_pb_image_container, .et_main_video_container').outerHeight(true) : 0;
height += $(this).find('.entry-title').outerHeight(true);
height += ($(this).find('.post-meta').length != 0) ? $(this).find('.post-meta').outerHeight(true) : 0;
height += ($(this).find('.post-content').length != 0) ? $(this).find('.post-content').outerHeight(true) : 0;

heights.push(height);
});

var max_height = Math.max.apply(Math,heights);

articles.each(function() {
$(this).height(max_height);
});
}

$(document).ajaxComplete(function() {
$('.et_blog_grid_equal_height').imagesLoaded().then(function() {
$('.et_blog_grid_equal_height').each(function(){
equalise_articles($(this));
});
});
});

$.fn.imagesLoaded = function() {
var $imgs = this.find('img[src!=""]');
var dfds = [];

if (!$imgs.length) {
return $.Deferred().resolve().promise();
}

$imgs.each(function(){
var dfd = $.Deferred();
dfds.push(dfd);
var img = new Image();

img.onload = function() {
dfd.resolve();
};

img.onerror = function() {
dfd.resolve();
};

img.src = this.src;
});

return $.when.apply($, dfds);
}
});
})(jQuery);
</script>

All Blog Grid articles, on each page of the Blog Module post listing, will get the height of the "tallest" article "box" on that page of the listing:

TIP:
If any of the articles has a "content overflow" problem where text goes out of the boundary of the article "box" - insert this CSS Code in the Custom CSS Box in the Divi > Theme Options page:

.et_blog_grid_equal_height article {
overflow: hidden;
}


Disclaimer:
This article works when Standard or Video Blog Posts are included in the Blog Module, using Audio Post format or any else Post Format will cause it to stop functioning.
