FRAME SIZE CHART
Frame sizing is very much a personal preference: some riders like them longer, others shorter. Here's a rough guide - if you have any questions remember we are here to help!3ft - 3ft 8" - best suited to a 16" BMX bike
3ft 8" - 4ft - best suited an 18" BMX bike
4ft - 5ft - 18" to 20" top tube
5ft - 5ft 4" - 20" to 20.25" top tube
5ft 4" - 5ft 8" - 20.25" to 21" top tube
5ft 8" - 6ft - 21" to 21.25" top tube
6ft plus - 21" top tube or longer
| Rider Height (in) | Rider Height (cm) | Top Tube Length |

| 5' | 152 | 20" |
| 5'3" | 160 | 20.5" |
| 5'6" | 167 | 20.75" |
| 5'9" | 175 | 21" |

FRAME GEOMETRY
Frame geometry can take a bit of understanding - but here at SourceBMX we are here to help! The first thing to understand is that BMX frame sizing is best measured by the length of the top tube - shown here as TT. Keep reading on to understand how the angles change how your frame will feel!
Head tube angle determines the angle of your forks. A steeper HT (i.e 75°and higher) will make the bike turn quicker than a mellower angle (i.e 74.5 and lower°). The more responsive the frame, the more twitchy it will feel, especially at high speed!
Seat tube angles don’t vary too much (around 71°) and affect the centre of gravity. The steeper the angle, the shorter your bike will feel. Some frames have a mellower seat tube angle (example 69˚) which makes for a longer frame without actually being longer and reduces how fast your frame turns.
The chain stay is essentially the length of the rear end of the bike. A shorter CS length will make the bike more responsive and a longer one more stable. As a rough guide a 13.5" long chain stay is about average.
Stand over height is essentially how high your frame is. A frame with a low standover height is more responsive and easier to 'throw around' whilst a high SO height is more stable; particularly useful when going fast.
