If the size of your floor plan is too big, you will see the notification "This floor plan is too big" when you click View live 
.
Note that attendees will not see this message because they access the floor plan view directly, not from the Designer.
A heavy floor plan may load slowly for some users and be less responsive than a regular one. In this article, we'll provide some tips on how to reduce the size of your floor plan and improve the loading speed.
Images in the floor plan
Overly large image files in a floor plan may cause it to become too unwieldy. If you get the "too big" notification, consider replacing your images using the following guidelines.
Image type
In general, PNG and JPG images are preferred, although our software also supports SVG files. If you use SVG images, ensure that they are not overly detailed or complex. Converting raster formats (PNG, JPG, BMP) to SVG through online converters can result in complicated image outlines requiring additional calculations.
Image size
You should always check the size of the images you are using in your floor plan to make sure they are not causing it to get too large. For background logos, the preferred size is about 512 x 512 pixels. For images uploaded to the Designer, especially larger images such as background images, you can use a resolution of up to 2048 x 2048 pixels.
It's important to note that the maximum safe resolution for Android devices is 4096 x 4096 pixels. Exceeding this resolution may cause display issues for Android users.
Designer elements
Reducing the number of elements in your design can help increase the performance of your floor plan. Multiple identical elements, such as chairs, can often be replaced with a generalized icon.
In addition, we recommend drawing your floor plan as close as possible to the top-left corner of your floor plan (0,0). The farther your elements are from that point, the larger the numbers become for each element coordinate. This can add up to 5% to the size of the floor plan.
Scaling and aligning
It is very important that any uploaded file you use for your map layout is scaled correctly. You will then be able to ensure that each object fits perfectly within your layout.
Each object on your floor plan should be sized accurately to the actual physical object that will be at the venue. Very large elements and the area map may not load well when viewed on mobile phones.
To check or change the size of an object, select it and check the "Properties" menu on the right side. You can then set the exact width and height of the object in your desired units.
You can use the grid to help you align objects and ensure your layout is accurate. The grid controls are at the bottom-right corner of the Designer. Make the grid visible, if it isn't already, and turn on the snap-to-grid option. Then, choose the grid size. A larger grid will help you align bigger objects, while a smaller grid will help you align elements with better precision.
Exhibitor display in a booth
Too many exhibitors displayed in a booth can cause issues with the floor plan loading. In order to prevent this, we control the way exhibitors are displayed in a booth. If your booth contains several exhibitors, the order of display is set according to these rules by default:
Following the order in which they were assigned to this booth
If there are less than 5 exhibitors in a booth, all their names are shown
If there are more than 5 then only their number ("8 exhibitors") is shown. You'll still see their names when clicking on the booth and in the exhibitor list.
Please note that a large number of exhibitors, having to display many exhibitor names within the booth and the length of exhibitors' names may affect the floor plan's performance. If you wish to show all the companies in booths, we recommend splitting big booths into several ones or using exhibitor tags.
