Increase Slider Height


First, love the theme. I am using it for two of my blogs!!

I tried looking for an answer to this and couldn’t find one that worked for me.

I just want to increase the default size of the slider height. I want it to be taller, i.e. take up more space on my page. Is there a way to do this? I know it is currently at 550, but I would like to try something like 700 if possible.

Thank you so much.

Hi @ashala101,

I hope you are well today and thank you for your question.

You can try achieving this by using the attached small plugin specially developed for you that contains following custom code.

function custom_activello_setup(){
    add_image_size( 'activello-slider', 1920, 700, true );
add_action( 'after_setup_theme', 'custom_activello_setup', 99 );

You can change the slider height 700 in the above plugin code to whatever you want.

Best Regards,

Thanks so much for responding.

I installed the plug-in but it doesn’t seem to be making a difference. Am I missing something?

Please make sure to activate it after installing.

Could you please share me your site URL where you are using it so that i can troubleshoot it?

Yes of course - it is

I visited your site and found the slider images have height only 550px as shown here

Please make sure the slider images have height 700px and try regenerating thumbnails using the below plugin.

Hi Movin,

I tried the plugin attached in the first reply, I have also changed the height. However i do not see any changes to the slider height. Please advice


Hey there,
I hope you’re doing well today

Admin Area -> Appearance -> Customize -> Additional CSS

.flexslider {
    height: 800px !important;
img.attachment-activello-slider.size-activello-slider.wp-post-image {
    height: 800px;

Best Regards,

I added the line successfully, however, the image stretched vertically.

You should use the slider images having height and width greater than what you have set in the above custom plugin code.

After activating custom plugin on your site please regenerate thumbnails using following plugin.

Thank you, the issue has been fixed with your guidance.=)

one more thing Movin, if say i like the slider to be full width instead of having white space on both sides how do i do that?

Hi Movin,
I have the same problem with the image of my slider that stretched vertically,but I think the images are bigger than the 1920 x 700 px size I set up. Could you check this for me please ?
Otherwise, I don’t understand what exact size of images I should take so that everything fits perfectly and the image is not cropped or stretched…

Thank you very much for your advice, it is SO helpful !!
