"Other" data in Iphone 5 .. how large should it be ?

i have 1.75 gb of other data i have deleted almost all to everything of my apps ,photos and videos im not sure if this amount of data is normal or if i have something wrong with my phone or not and yes i have also checked my usage section and the largest app i have is twitter which i have deleted and added again and keeps on reaching a whooping 251MB which for twitter i assume its normal ?
