Hello Geert,

Thank you for reaching out to us.

Unfortunately, currently, this feature is not built-in in Amelia.

this can maybe be achieved with some custom CSS.

Our support does not fully provide customization solutions, but we can try to provide some basic CSS in situations like this.

For manipulating the width of the "outer Booking container", you can try this CSS:

.amelia-v2-booking #amelia-container.am-fs__wrapper {
    max-width: 1200px !important;
    width: 100%;
    height: 560px;
    margin: 99px auto;
    border-radius: 8px;
    box-shadow: 0 30px 40px #0000001f;
}

For example, on our Demo page, if i add that CSS, the outer container expands like this :

Just the background colour we set is transparent, so it is not very visible on our page,

 but that width can be changed like that.

Now, if you also wish to manipulate this "inner Booking container width", you can use this CSS selector :

.amelia-v2-booking #amelia-container .am-fs__main {
    
    max-width: 1200px;
    width: 100%;
}

If i add that to our Demo, here is the result :

As you see, we have successfully changed the width this way.

The main property to edit is "max-width" with a fixed pixel value.

Let us know if that works for you.

If you wish to see a built-in solution for users to choose the Booking Form width from the Amelia's Customize interface, 

please feel free to search through our feature suggestion page, 

 to see if someone may be already suggested this feature. If you can't see it, feel free to add your suggestion there, and as more people vote, the feature will move higher on the priority list.

You can certainly follow our changeLog page if you'd like, where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

We wish you all the best.

Have a nice day.
