																	Can you fit a king mattress on a california king frame. 
									
	
		
	
																	A king bed frame holds a mattress that is 76 inches wide and 80 inches long. 
																	The key to making this work is to make it look like it s intentional by turning it into a platform bed. 
																	We currently have a california king bed. 
																	These two mattresses differ in their dimensions. 
															
													
									
	
		
	
																	It is perfect for those who think that 78 8 inches width of a king bed is too much. 
																	California king sized bed frames typically measure 72 inches wide and 83 5 inches in length. 
																	You can easily spot the difference because it is longer and narrower than a king sized bed. 
																	A regular king sized mattress is 76 wide and 80 long while the california king is 72 wide and 84 long.
