Leaders fall in several categories. These all serve the same purpose: transmitting the energy fra the fly line to the fly in a gentle, yet firm way. The different types each have their advantages and disadvantages, and selecting one is often a question of compromises.

- Tapered
The tapered leader is probably the most common. It consists of one piece of monofile line, that has been drawn to a taper from a thick base to a thin tip, that are made the normal range of tippet weights. - Knotted
The knotted leader has been tied together by several pieces of monofile line to form a similar taper. It's inexpensive and can be made to any taper, thickness, stiffness and hence purpose. There's a ton of formulas for knotted leaders in our online tool LeaderCalc. - Braided
The braided leader is made from thin braided monofile strands. It's normally tapered by leaving out more and more strands towards the tip. The braided leaders are generally expensive, but also offer a supple presentation and high knot resistance - Twined
The furled or twined leader has the advantage of the braided leader (it's even better actually). It's expensive when purchased, but inexpensive to make yourself matching the price of the knotted one. Here's a detailed description on how to make such leaders.
Leader and tippet sizes
| 'X-size' | 0X | 1X | 2X | 3X | 4X | 5X | 6X | 7X | 8X |
| Tip dia. (mm) | 0.28 | 0.26 | 0.23 | 0.20 | 0.18 | 0.15 | 0.13 | 0.10 | 0.07 |
| Tip dia. (inches) | 0.011 | 0.010 | 0.009 | 0.008 | 0.007 | 0.006 | 0.005 | 0.004 | 0.003 |

| Test(lb.) | 15 | 12 | 10 | 7 | 5 | 4 | 3 | 2 | 1 |
The test weights are examples from Sunline (Siglon and other brands) and may vary quite a bit from brand to brand.

Todd,
You usually
Todd,
You usually use either the same tippet size as the leader or slightly thinner. The 4X will probably refer to the thickness of your leader in the thin end, and by adding a 5X tippet, your taper it further down, while a 4X tippet will continue the same thickness as the tip of the leader.
Hope this helps.
Martin
I need to know what
I need to know what size tippet to use with a leader size of 4X ..
