Is there a limit on the number of columns you can have in a sheet. I have 221 and I am seeing some issues, not sure if related. I am opening up a form that is linked to a sheet with 221 columns. when I do that, the components are not displaying (I have no visibility settings on the first two components). Also when I click on the + to add component, I am not seeing any of the components, but when I go to a different sheet then its seems to be working. ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/f/a/faf94362f2f501c6f5b69b4278e0b252b416065e.png) ---

There might be a point where things start falling. I recall @Darren_Murphy have an app with a large number of columns, I’m not sure it reaches 221. Why do you have that many columns, though? ---

> [@Dan\_San](#): > > Is there a limit on the number of columns you can have in a sheet. I have 221 and I am seeing some issues, not sure if related. Basic or computed columns? I have apps with several hundred _computed_ columns in a single table, and I’ve seen Apps with over 1000. But I don’t think I’ve ever seen more than about 100 non-computed columns. If they are columns that contain actual data and that’s combined with a large row count, then I could imagine that causing issues. Might be best to reach out to Glide Support. ---

Its basic data “boolean” columns. Its check boxes. I have a vehicle inspection app, so when a driver starts his shift he needs to do an inspection. Depending on the vehicle he will be driving, a different checklist will appear. I have about 7 different type of inspections, they choose the inspection type and then the relevant components appear. I have reached out to support. If I have to, I will have to split it across 7 different sheets and forms but wanted to keep it in a single file for easier reporting. ARE YOU SAYING that the basic data fields add more weight to the app then computed columns ? This is interesting, I’ve been shy of using too many computed columns. ---

Well I can’t say for certain, but it seems logical to me that they would. Non computed columns contain actual data - bits and bytes - that is always there. Where as computed columns only contain data when needed. Maybe it’s a bit like comparing apples and oranges, in that they each affect performance in a different way. Non computed columns affect the total data payload size, where as computed columns affect the processing load. That said, I wouldn’t imagine that a bunch of boolean columns could have much impact at all.
